The dream of the self-driving car \u2014 you get in, program your destination, ease the seat back, and let the car take you where you need to go. Read a book. Maybe take a nap or play a game on the in-car entertainment screen. Regardless, you will not need to watch the road. The car will get you there and back safely.<\/p>\n
Are we there yet? If not, when will we be? Automation and autonomous driving are complex subjects. What engineers can safely deliver doesn\u2019t always match what marketers want to sell.<\/p>\n
Mercedes-Benz recently announced its Level three Drive Pilot self-driving technology. That means the car can drive itself under limited conditions. Still, Tesla This guide will walk you through what you need to know about automotive autopilot, self-driving technology, and driver aids today and tomorrow.<\/p>\n Self-driving cars are vehicles that fully operate without human intervention. Still, when discussing automotive assistance systems\u2019 terminology, no one agrees on what to call anything in this field. From engineering jargon to marketing speak, the lingo continues to evolve.<\/p>\n Roughly speaking, you can sort the technologies people might refer to as self-driving into two categories \u2014 driver support and automation systems. Read on to see how they differ.<\/p>\n SAE International, a global association of engineers and related technical experts in the aerospace, automotive, and commercial vehicle industries, has laid out a useful framework for thinking about self-driving systems. It lists them as levels zero to five. However, not every level is classified as autonomous driving.<\/p>\n Driver support technology reduces the workload on the driver. Today, most automakers sell various driver support systems, either as standard equipment or as car options. These include intelligent or adaptive cruise control, lane-keeping assists, and hands-free capability.<\/p>\n Autonomous systems do the driving for you. Automakers today are pushing toward this technology. Waymo, a sister company to Google, is testing autonomous ride-share vehicles in places like Phoenix and San Francisco using converted Chrysler Pacifica minivans and other vehicles. Los Angeles may not be far behind. General Motors\u2019 Cruise unit also offers ride-share vehicles in places like Phoenix, San Francisco, and Austin.<\/p>\n SAE\u00a0sorts the technologies into levels labeled zero through five (OK, even automotive engineers don\u2019t always do the logical thing).<\/p>\n However, not every level is classified as autonomous driving. According to SAE, Levels 0 through 2 are considered driver support features, while Levels three through 5 are classified as having autonomous capability.<\/p>\n At Level 0, the car reacts only to the driver\u2019s input. Even if it uses sensors to warn you of surrounding traffic, like a blind-spot alert system or a lane-departure warning, it still has no self-driving capability to correct or counter the perceived threat.<\/p>\n At Level 1, your car can intervene slightly in your driving in an attempt to keep you safe. A lane-keeping system that helps steer to center you in a lane is a Level 1 technology.<\/p>\n At Level 2, features communicate with one another, and more than one can be active simultaneously. An example of this autonomous technology is an adaptive cruise control system that adjusts your speed to keep you a certain distance from the car ahead while centering the car in its lane.<\/p>\n Currently, Level 2 systems are the most sophisticated technology sold on cars in America. Some automakers describe these systems in ways that make them seem more advanced than Level 2 standards because they allow drivers to take their hands off the steering wheel briefly. Systems like Tesla\u2019s Full Self-Driving and GM\u2019s Level 2 systems require drivers to keep their eyes focused ahead. Drivers need to be ready at all times to take over control of the car at a moment\u2019s notice.<\/p>\n At\u00a0Level 3, the car drives itself under limited conditions, and the driver is not driving. However, drivers must remain aware and be prepared to take over. A Level three autonomous vehicle will manage speed and steering, negotiate curves, and follow a route. However, drivers must be ready and capable of taking control.<\/p>\n According to\u00a0Honda\u00a0 Mercedes says its\u00a0Drive Pilot technology\u00a0is a Level three system. Nevada\u2019s DMV approved Drive Pilot, and the system can take over driving up to certain speeds, allowing drivers to search the Internet or watch a movie. According to Mercedes-Benz, the system will be available in its 2024 S-Class and EQS Sedan models and could also be available in California later this year.<\/p>\n See<\/strong>: The 2023 Mercedes-Benz EQS sedan: A luxurious and high-tech EV with thrilling performance<\/p>\n At Level 4, the car can drive itself in a fixed loop on known roads. The rider is not required to take over driving at any time. These vehicles may or may not have a steering wheel or pedals. In some places, Level 4 driverless ride-share vehicles (like Waymo\u2019s) are in limited testing. But they are not yet approved for general use in any state.<\/p>\n At\u00a0Level 5, the car can drive itself under any conditions and on any road. These vehicles do not have steering wheels or pedals. At this point, Level 5 systems are theoretical.<\/p>\n Don\u2019t miss:<\/strong> Driverless cars are driving San Francisco crazy \u2014 \u2018They are not ready for prime time\u2019<\/p>\n Recently, Tesla recalled its full self-self driving beta technology in all its electric vehicles after the National Highway Traffic Safety Administration said it\u2019s unsafe to use.<\/p>\n Tesla advertises its automation systems more than any other U.S. automaker. Still, its advertising materials state, \u201cAutopilot and Full Self-Driving Capability are intended for use with a fully attentive driver, who has their hands on the wheel and is prepared to take over at any moment. While these features are designed to become more capable over time, the currently enabled features do not make the vehicle autonomous.\u201d<\/p>\n Most self-driving systems currently for sale in the U.S. are SAE Level 2 or lower. Removing your attention from driving while behind the wheel of any car currently sold with this technology is unsafe. However, it is safe to briefly remove your hands from the wheel with some Level 2 systems under certain conditions. But you should remain prepared to take over the driving at a moment\u2019s notice.<\/p>\n See<\/strong>: Americans are becoming more afraid of self-driving cars, study says<\/p>\n Yes. Always. Even when using driving assist technology in Levels 0 to 3, you need to be prepared to take over driving at any moment.<\/p>\n However, when using low-speed applications, including self-parking features, keeping your eyes on the road or staying inside the vehicle may not be needed. For example, some luxury brands offer a self-parking remote that handles this maneuver for things like parallel parking.<\/p>\n Plus<\/strong>: American drivers are falling out of love with the latest car designs and tech, study finds<\/p>\n Virtually every automaker selling cars in the U.S. today offers driver-assistance systems that can reduce the workload on the driver. These include adaptive cruise control that can adjust speed to maintain distance from the car ahead or automatic emergency braking that can slow or stop the car to avoid hitting a vehicle or pedestrian or reduce the severity of a crash.<\/p>\n None of these systems are so reliable that the driver can take their attention from the task of driving, though.<\/p>\n Many manufacturers currently market systems up to and including Level 2 automation. This approach combines adaptive cruise control and lane-keeping assist into a system that requires that the driver keep their hands on the wheel but relieves some of the driver\u2019s workload.<\/p>\n Also see (March 2023):<\/strong> Self-driving truck startup Embark says it may go bust, shares plunge 33%<\/p>\n A prime example is cruise control with stop-and-go capability that allows the driver to negotiate heavy traffic without using the pedals.<\/p>\n Here\u2019s a breakdown of what to expect from several of them.<\/p>\n Ford Like Tesla\u2019s Autopilot and GM\u2019s Super Cruise systems, BlueCruise pairs an adaptive cruise control with lane-keeping assistance. It allows drivers to temporarily remove their hands from the wheel while keeping their eyes on the road.<\/p>\n BlueCruise automatically steers the vehicle using more than 100,000 miles of pre-mapped roads stored in the system. In BlueCruise-equipped cars, the driver\u2019s instrument cluster switches to a blue background when driving on a road where the system can be activated.<\/p>\n A subscription to BlueCruise costs $600 for three years. However, you must buy an option package with all the necessary equipment to use it. Costs can be as much as $3,200, depending on the Ford model.<\/p>\n General Motors offers its own advanced driver assistance system, an SAE Level 2 system called Super Cruise. Like Tesla\u2019s Autopilot, Super Cruise includes an adaptive cruise control that will speed up and slow down the vehicle to maintain a driver-selected distance from the vehicle ahead. It also has a lane-keeping system that tries to center the car in its lane even through curves in the road, and automatic emergency braking that brakes the car in an attempt to avert a collision.<\/p>\n Super Cruise requires the driver to stay alert and keep their hands near the wheel. It includes a driver monitoring system that watches the driver\u2019s eyes and warns them if their attention seems to be drifting from the road. GM says, \u201cSuper Cruise allows the driver to drive hands-free when compatible road driving conditions allow the feature to be available. But the driver still needs to pay close attention to the road. Even while using the Super Cruise driver assistance technology, drivers should always pay attention while driving and not use a hand-held device.\u201d<\/p>\n You can find Super Cruise on a variety of Cadillac vehicles and others like the Chevy Bolt and Bolt EUV electric vehicles. Super Cruise is free for the first three years but requires a subscription after that.<\/p>\n Of note, Super Cruise works only on roads mapped by GM. The company mapped at least 200,000 miles of roads in the U.S. and Canada using lidar mapping technology.<\/p>\n Don\u2019t miss:<\/strong> California looks at vehicles\u2019 data collection amid privacy concerns<\/p>\n Mercedes-Benz\u2019s Distronic Plus with Steering Assist also combines adaptive cruise control with a lane-centering system. In keeping with Mercedes\u2019 autobahn image, it functions at up to 120 mph and warns drivers if they are about to be passed.<\/p>\n Another feature, called Parktronic, allows drivers to follow the car\u2019s commands under 20 mph as it self-parks the vehicle. The driver keeps control of the car with the gas and brake pedals. The driver needs to put the car in drive or reverse as it drives and steers itself into a parking space.<\/p>\n Mercedes-Benz recently unveiled its Drive Pilot technology as a Level three system for use in Nevada. The system can take over driving up to certain speeds, allowing drivers to do certain tasks and take their eyes off the road. The system could become available in California later this year. According to Mercedes-Benz, the system will be available in its 2024 S-Class and EQS Sedan models.<\/p>\n Also see: <\/strong>Who\u2019s most likely to lose their job to AI?<\/p>\n Nissan Newer versions use the vehicle\u2019s navigation system information to slow for curves ahead and prompt the driver to adjust for posted speed limits. While it will keep the car centered in its lane, it will not steer the car through curves like Kia\u2019s Subaru\u2019s Tesla markets its evolving suite of self-driving technologies more aggressively than any other automaker. This has led to current confusion about what level of automation Tesla cars are capable of. The electric car company sells the systems under two names: Autopilot, and Full Self-Driving.<\/p>\n Autopilot<\/strong>: Autopilot is a traffic-aware cruise control system that accelerates and slows the car to match the speed of the cars around it, combined with a lane-keeping assist system that centers the car in a clearly marked lane. That\u2019s all it is. The marketing name \u201cAutopilot\u201d may make it sound considerably more advanced. But it is similar to adaptive cruise control and lane-keeping assist systems offered by most automakers, like Nissan\u2019s ProPilot or Subaru\u2019s EyeSight.<\/p>\n Older Teslas use\u00a0torque\u00a0sensors in the steering wheel to monitor the driver\u2019s attention level and promptly alert them if their attention seems to be waning. Newer models use a more accurate camera for the same purpose.<\/p>\n Full Self-Driving<\/strong>: Tesla\u2019s Full Self-Driving is considerably more sophisticated. Despite its name, it does not possess SAE Level 5 self-driving capability. Full Self-Driving can park the car in a parking space, back it out of a parking space, and change lanes on its own at highway speeds. A more advanced system in beta testing can slow the car for stop signs and traffic lights and navigate highway on-ramps and offramps. Tesla regularly sends updates to this system remotely to cars currently involved in the beta test.<\/p>\n However, Tesla recently announced a\u00a0recall of the Full Self-driving software\u00a0and paused a rollout of the system. While the recall doesn\u2019t take it off the road,\u00a0it promises a software update to correct specific problems identified by the National Highway Traffic Safety Administration.\u00a0\u00a0<\/p>\n Full Self-Driving does not allow drivers to take their attention off the road. They may temporarily take their hands from the wheel but should be prepared to take over driving at any moment. Tesla\u2019s marketing materials caution, \u201cThe currently enabled Autopilot and Full Self-Driving features require active driver supervision and do not make the vehicle autonomous.\u201d<\/p>\n Full Self-Driving is a costly option, even by luxury car standards. As of this writing, the Tesla self-driving price for the feature adds $15,000 to the total cost, or a $199\/month subscription. Tesla promises to update it regularly in hopes of eventually releasing an SAE Level 5 autonomous driving system to everyone who has purchased Full Self-Driving.<\/p>\n However, in a recent letter to California state regulators, Tesla said that Full Self-Driving would remain at Level 2. The company said it did \u201cnot expect significant enhancements\u201d that would \u201cshift the responsibility for the entire dynamic driving task to the system.\u201d Instead, the letter said, Full Self-Driving \u201cwill continue to be an SAE Level 2, advanced driver assistance feature.\u201d<\/p>\n Consumers should be aware that the company has told shoppers it will someday have Level 5 capability and has told government regulators that it would not.<\/p>\n Plus<\/strong>: <\/strong>18 new EVs to watch for in 2024<\/p>\n Volvo\u2019s Luxury automakers have begun developing semi-autonomous driving systems specifically for use in heavy traffic. They allow the driver to relax their attention and let the car accelerate and brake to keep its place in traffic, but systems work only at lower speeds.<\/p>\n BMW\u2019s Audi is developing its own Traffic Jam Pilot that, it says, should allow drivers to remove their hands from the wheel below 37 mph. But that system has not received regulatory approval.<\/p>\n Read: <\/strong>5 reasons you should hold off on buying an EV<\/p>\n Engineers from more than a dozen companies are testing self-driving systems in hopes of producing an SAE Level 5 self-driving car. It seems safe to predict that the technology is coming.<\/p>\n But the engineering challenge of getting there is immense. A car that can drive itself on well-maintained roads may make a critical mistake on poorly maintained roads. What if a car that can react safely to normal traffic may not react safely to unusual situations? A car that can do everything engineers ask of it may fail when presented with a problem they never considered. In one recent incident, a self-driving car in testing was baffled by a truck bed full of traffic signs being delivered to a construction site. The car had no idea what to do.<\/p>\n Beyond the engineering challenge, 50 state laws, plus the District of Columbia, must adapt to decide safety and liability issues before self-driving cars become common.<\/p>\n
