They begin with no automation and wrap up with full automation, including vehicles without pedals or steering wheels. Adaptive cruise control works by using a series of sensors in and all around your vehicle to see the other vehicles on the road. The sensors can determine when a vehicle is getting too close to you and signal to your system that you have to slow down or adapt to a change in scenario. Overseas, some manufacturers are offering Level 2 self-driving systems, with Cadillac’s Super Cruise and Nissan’s ProPilot capable of autonomously driving vehicles along a single lane on freeways and motorways. With that said, some carmakers allow their systems to drift over the set speed when travelling downhill.
Challenges Facing Consumer ACC Adoption
It's worth getting the upgrade for most people, and once you have it, you will not want to drive without it. Sure, you might not be able to take the stress out of sitting in rush-hour traffic on a Friday, or any day for that matter, but you can at least still set it and forget under normal driving conditions. Drivers should know that they are responsible for what happens when they are behind the wheel. Every company makes sure to include an asterisk and notice that drivers are still needing to be actively engaged in driving. 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.

A conventional cruise control system does not automatically keep a set distance away from the car in front, and it is indicated by a similar logo without the car next to the speedometer. A tip to know if your car has adaptive cruise control or regular cruise control is to look for the “gap distance” button, which usually shows a symbol of a car with horizontal distance bars in front. This button will determine how much space your car leaves between its front bumper and the rear of the car it is following. The systems use lasers, radar, cameras, or a combination of those. 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.

Well the policy wording of most insurers doesn’t tend to name any car features specifically. Insurers do include the make and model of the vehicle within their underwriting algorithms though, so it would not be unreasonable to expect that a vehicle having ACC would be risk-assessed and priced accordingly. Similarly, being able to set the car to a particular speed will make it easier for you to stay safely within the speed limit, and less likely to pick up fines or penalty points. If you turn on Adaptive Cruise Control and do not see the trailering icon in the DIC when you try to change your gap settings, your vehicle is not properly equipped to use Adaptive Cruise Control while trailering.
Keith earned a master’s degree in public health from Tufts University. Adaptive cruise control is an impressive technology that you can add to your vehicle to make it more capable. It's only available on some vehicles today, but the ones you upgrade with it will perform better thanks to the improvement.
ACC Availability Across Vehicle Makes
Bad weather that affects road surface traction or visibility may impact its performance. Also, if the forward-looking camera or radar sensors, if equipped, are obstructed in any way, the system will not perform as expected. Adaptive Cruise Control systems may not perform as expected where lighting is poor or when following vehicles with unusual shapes. As terrific a technological leap as adaptive cruise control is, some minor disadvantages should be noted. One is that there is not one standard in place for all makes and models of cars.
Is Cruise Control Safe?
If your vehicle has this available feature, Adaptive Cruise Control† allows you to set a cruise control speed and automatically follow a detected vehicle ahead at a driver-selected following gap. If no vehicle is detected in your path, the feature works like regular cruise control. Just as with traditional cruise control, the adaptive cruise control system requires drivers to choose their preferred speed. Next, ACC requires drivers to set their preferred following distance from the vehicle’s pre-set options. Radar-based ACC is often sold together with a precrash system,[43] which warns the driver and/or provides brake support if there is a high risk of a collision. Also in certain cars, it is incorporated with a lane maintaining system which provides a power steering assist to reduce steering input burden on corners when the cruise control system is activated.
Level 3 – If Level 2 is partial self-driving, Level 3 is conditional full automation. A Level 3 self-driving system uses a wide spectrum of driver-assistance features and artificial intelligence (AI). These technologies collude to react to and make decisions about the vehicles’ ever-changing situations. In a Level 3 vehicle, the driver can completely surrender control of the vehicle’s operation on specific roads. The driver must be prepared to resume control in case of an emergency but otherwise doesn’t have command of the car.
For example, the Set and Accelerate functions are often incorporated into the same button or toggle. Although individual carmakers may provide differing controls, the fundamentals of a basic cruise control system remain the same. That is, the driver manually sets and then can adjust the desired speed, while the cruise control system automatically responds to the driver’s input via steering-wheel-mounted controls.
In a Consumer Reports survey, 85 percent of drivers with Adaptive Cruise Control (ACC) on their vehicles said they were very satisfied with it. What’s more, 19 percent said their ACC system helped to avoid a crash. If you’re the type of driver who loves having the latest bit of tech in your car then an ACC system is a must-have. Similarly, if you spend a lot of time travelling on busy motorways, ACC can provide welcome assistance when navigating traffic.
Another advantage of having an adaptive cruise control system on a car with an automatic transmission is that the car will actually take care of itself in stop-and-go traffic. When traffic slows down, the system will detect the car in front of you and adjust to its speed, effectively doing the “traffic dance” for you. However, for cars with a manual transmission, this feature is not included since you would have to depress the clutch and shift gears manually in order to keep the car going. At first, it might seem like a manual transmission and adaptive cruise control wouldn’t work well together. We say this because, unlike regular cruise control, adaptive cruise control regulates the car’s speed. And when the car slows down, the RPMs will drop, which would cause a manual transmission car to either bog or stall.
So when ACC acts up, check for sensor obstructions, misalignment, and also ask your dealer to verify the latest software is installed. But it‘s impossible to evaluate every edge case scenario an ACC system may encounter once on the road. Overall Mercedes sets the benchmark for ACC performance and capability in my opinion, with German automakers continuing to lead the way. Automotive engineers tweaked around the edges of cruise control for the next 35 years.
