I just drove a car with Active Cruise Control and it’s cool.
On the highway, I set the speed at 65mph and the ACC kept the right distance between my car and the traffic ahead. Most of the time I was actually going about 60. When the traffic slowed down, the car slowed down; traffic faster, car goes faster. And I was able to set my preferred distance from the other cars, within a certain range. (At the shortest distance allowed, I felt that I was tailgating.) If there were no cars ahead, then it operated pretty much like regular cruise control. I could still accelerate using the pedal and it would deactivate if I hit the brake, but I could press Resume immediately since the car would accelerate only to the point where it was a safe distance from the car ahead.
Obviously, you still have to drive the car. The ACC will never apply more than 10% braking so there is no automatic panic stop.
I’ve never been a big fan of cruise control but this new system is much more useful, especially on long trips in moderately heavy highway traffic where regular cruise control is practically useless.
What do you think?
