I drove a rental a year or so ago, and it had adaptive cruise control. This is where it would be like cruise control, except it would slow down if a car in front of you was going slower, and adjust the car speed to match their speed. I'd never seen this before. I found that I couldn't really use it, because the distance you could set for it to follow the car in front of you was too close for my taste. I found you could decrease the distance by quite a bit, but I wasn't able to increase it to what I wanted.
