It scared the snot out of me. I was on a 1 way road and the car in front of me was turning left. There is no way I was going to hit him though I might have been closer than is polite, and in fact by the time it hit the brakes I was past him. But it slammed on the brakes anyway. Thank god I didn't get rear-ended. Is there a way to turn this feature off permanently? I hate it. I don't want some buggy-*** computer or defective sensor deciding to slam on the brakes at random, it's totally unacceptable.
