I don't use the brake. Had it over a year and I'd bet I've put my foot on the brake less than 20 times. All those for lights changing when I'm close, that sort of thing. Came home during rush today. Didn't use the brake. With a little practice you can creep along at 1mph in traffic. With a little more practice, you can creep along at 0 mph.I use adaptive cruise in stop & go traffic so I don't have move my foot back an forth from gas to brake. I set it to 10 mph in creeping traffic & adjust spacing to 2 car lengths. With all the road construction I use it often.
But letting it do the creep and stop is an interesting idea. I might try it for the creep and stop but not for the stop then 20/30, then quick stop, then 20/30 etc. Too nerve wracking.
