I now recall the van would lock up at less than 15 mph. But as it was a steep hill, it got over 15 mph easily, then the ABS held me at about 15 mph so long as I let off the brakes long enough to get the wheels turning. If it slowed down too much I had to let up or go into a skid. And it was on glare ice--this was after the ice storm a few years ago that made national headlines.
With as sophisticated as cars are getting, I wonder if the more high tech systems can "learn" the amount of available traction and ease on the brake pressure instead of locking up/unlocking constantly.
