Searched the forum but didnt find anything on this...
Traffic opened up in front of me so I laid into it and at the exact same instant a guy pulled into my lane just ahead of me. I jammed on the brakes, and felt the ABS pulsing (tires were screeching too.) Then comes the weird part - I let off the brakes, but for another half-second the car kept braking - hard! That was a half second of terror because I was picturing the car behind me slamming into me. Luckily no one was close, but now I have less confidence driving the car iif it is going to decide to brake hard wth my foot off the pedal. Any ideas? Was it because I went from hard acceleration to hard braking? Was it the esp detecting wheelspin while braking and it decided to keep braking? (ESP was "off") Brake pedal sticking?

On a side note - why do people click on their turn signals AS they are changing lanes instead of before? At that point I can already see they are turning so doesn't that defeat the purpose of signaling a turn?
