When a system is controlling a car’s speed and steering, there’s a risk that its driver might feel more free to pick up a cell phone, eat a messy burger, or engage in other reckless, distracting behavior. That’s why we think it’s essential that ADA systems use direct driver monitoring systems (DDMS) to make sure the driver is paying attention to the road. A good system will encourage the driver to stay actively engaged, such as by allowing the driver to give steering inputs without fear of the LCA function shutting off.
Camera-Based Adaptive Cruise Control
By contrast, Nissan/Infiniti’s confusing and poorly labeled symbols on the steering wheel make ProPILOT Assist and the updated ProPILOT Assist 2.0 unintuitive to use and hurt its “ease of use” score. CR expands the tract at its Auto Test Center to help evaluate advanced auto technology. Make sure to also read our article about popular cars with adjustable back seats.
Keeping the Driver Engaged
Toyota, Honda and Mazda, for instance, provide it standard on all trim levels on nearly all their cars. If traffic slows to a stop, most ACC systems will bring the car to a complete stop, then bring it back up to speed when traffic gets going again. Others work only within certain speeds and/or might not start to accelerate automatically. Level 2 – To qualify as Level 2, a vehicle must have at least two driver-assistance technologies. This typically includes ACC and another technology like lane-centering assist or lane-keeping assist. With these technologies, the vehicle can steer, accelerate, and brake on its own in certain conditions.
Types of Sensors for Adaptive Cruise Control
Some call it adaptive cruise control as the root and then tack something onto it. As stated earlier, some systems will bring your vehicle to a complete stop to match traffic flow. Even more intelligent systems can then accelerate as the traffic flow resumes. Radar-based sensors can be hidden behind plastic fascias; however, the fascias may look different from a vehicle without the feature.

ADA systems can also have safety benefits, such as potentially keeping you from crossing over a lane line into opposing traffic during a moment of inattention. Mercedes offers one of the most comprehensive adaptive cruise control and driver-assistance suites of any automaker. Its latest Distronic Plus system can keep up with traffic, but also brake the car to a full stop in stop-and-go situations. The system will automatically resume driving if the car remains stopped for less than three seconds; longer stops require a tap of the accelerator pedal or of the cruise control’s “resume” button. A steering-assist feature helps keep the car centered in its lane, and certain versions of the system can initiate lane changes. Driving in heavy traffic or keeping a safe distance to the preceding vehicle calls for a high level of concentration.
Adaptive Cruise Control: What is ACC in ADAS?
Of course, the need for them to pay attention to the road ahead remained, as cars in front could still brake or suddenly cut in. Adaptive cruise control systems vary in sophistication from carmaker to carmaker and sometimes even model to model. For example, Genesis calls it Smart Cruise Control, while BMW identifies it as Distance Control. However, in a nutshell, the feature holds a safe preset speed while maintaining a safe following distance from the traffic before it. Systems with multiple sensors can practice sensor fusion to integrate the data to improve safety and/or driving experience. GPS data can inform the system of geographic features such as a freeway offramp.
Adaptive cruise control automatically controls the acceleration and braking of a vehicle. Yes, you will find aftermarket adaptive cruise control kits available. Depending on the features, they range in cost from $250 to nearly $4,000.
This tells the driver that either the system is steering or the driver, but you can’t have it both ways. When it comes to LCA, the systems from Ford, Mercedes-Benz, and Tesla all gave smooth steering inputs and did a good job of keeping the car at or near the center of the lane on both straight and curvy roads. This type of performance gives confidence to the driver that these systems are highly capable. We only included vehicles in our testing that were equipped with a system that allows for the simultaneous use of ACC and LCA at highway speeds. Models from Mazda, Porsche, Stellantis (Alfa Romeo, Chrysler, Dodge, Fiat, Jeep, Ram) were not included because we didn’t have a vehicle equipped with these features in our fleet when the tests were conducted.
Popular Used Vehicles
A study of 40 drivers by the Insurance Institute for Highway Safety (IIHS) found that they were more likely to speed when equipped with ACC. Because it’s not an autonomous car, those with stop and go capabilities will only “go” again within three seconds if traffic flow allows. If it’s longer than three seconds, driver action is needed to re-engage the system. In a Consumer Reports survey, 85 percent of drivers with Adaptive Cruise Control (ACC) on their vehicles said they were very satisfied with it.
CR safety experts say that this type of DDMS is key to the safety of any ADA system—and, in fact, CR awards extra points to the Overall Score of tested models whose ADA systems are adequately equipped. Starting with 2024 model-year vehicles, we will deduct points if an ADA system doesn’t have adequate DDMS. Right now, only Ford and GM’s systems meet our criteria for earning additional points, but others could be available soon.

Following a test run of the service last week, Cruise has released a video (below) showing the reaction of the very first passengers as they rode through the streets of the Californian city in a vehicle that had nobody behind the wheel. The achievement comes just 15 months after the company’s first fully driverless ride, during which time it also launched San Francisco’s first paid driverless robotaxi service.
