Adaptive Cruise is life-changing. I couldn't go back to normal cruise.

A major downside to Adaptive Cruise is when another driver uses your gap to change into your lane, and your car slams on its breaks because suddenly their car is just inches away from yours.

Recklessly aggressive drivers are learning they can take abuse these safety features in the cars of other drivers, making roadways potentially more unsafe.

Different cars have different behaviors here. My father has a Toyota Camry, and his will slam on the brakes, while mine, a Mazda 3, will much more gradually slow down and slowly increase the space until the gap is restored. It also seems to have a much more fluid sense for how big that gap should be.

I love my Mazda ACC and it will be a major criteria point in future car buying decisions.

What are you saying, you want it to crash into them for you? That's a major downside?

I'm not parent, but just a note from me: I drove a brand new Volvo XC40 last week that had adaptive cruise control. If someone just cut in to the front of me the car slammed on its brakes even if it wasn't necessary. The car could just as easily slow down gradually until necessary space was free in front of the car (as I usually do when I don't have adaptive cruise control).

Try Mazda, they're much better in that regard.
