The one time I think I needed ABS it didn't kick in or maybe it did but I don't recall feeling that pulsing sensation or change in brake pedal height as I had my foot firmly planted on the brake. Not paying attention (<-- Mistake #1 (can't fix stupid) ) I was about to go right through a stop sign at roughly 40mph. It was one of those "What a nice day...LA LA LA...OH SH*T Stop sign going by!!!" moments. I hit the brakes, hard. I come to a screeching halt, screeching because my brakes locked up. I laid a nice path of rubber on the road and managed to stop only half-way through the stop sign. I did stop in a straight line, no turning. However, on the track very quickly slowing down from 140mph or so to make a left turn onto an infield road course (pocono) I can feel my ABS working, no lockup, but I'm braking in a straight line not in the turn (obviously).
See.....ABS doesn't even work.
