One time my car decided that I was going to crash into one of those water tank things at a fork in a highway (actually, this was at a merge, on a curve, which is odd because you don't expect that) and it started doing it's alerting thing, and I had to swerve just so it would stop thinking I was going to crash into it. It was a curving merge, so briefly the car thought that I was driving towards an obstacle, but as long as I stayed in my lane that was never going to happen. That incident gave pause. If the brakes had engaged, might that have caused a crash?
