My Chevy Sonic has some kind of automatic braking feature. It kicked on for me once and probably prevented an accident. Edit Actually, I think it's not detecting a possible collision but recognizing that I slammed on the brakes and helping me push harder? Either way I wasn't braking hard enough at first and the car just took over.
