This morning I was driving my son and his friend on a fairly curvy 2 lane road doing about 50. A bicyclist in the bike lane a few cars ahead of us crashes and flies out into our lane. The cars in front of me lock up their brakes. Unfortunately, at that moment I was changing radio stations and didn't see it. The car's collision avoidance system kicks in, alerts me and applies the brakes so I don't hit the stopped car in front of me. Pretty amazing! Thanks Tesla!
