This is a bad thread in a good way. Bad because its unfortunate, but good to teach others.
That's an interesting thought. I don't know how the car would know it's still moving when all wheels are locked... I don't have GPS. Car did slow down sufficiently to 5mph so if the wheels locked maybe it just thought the car stopped. I think motion sensors only sense acceleration/deceleration, not constant speed.
Anyway, I still have no conclusion if my tires were sliding or if my brakes were sliding.
The day after the accident, I tried stomping on the brake as I was coming out of the parking lot and found that my impreza slid the first 2 times with no ABS, and the follow 3 times ABS engaged. All 5 test, I was going about 5mph.
