Eh, then you need to be more careful about how you're driving in heavy snow. ABS or not, I've never had that problem. The only time something like that happened to me was on solid ice. In the middle of a bad storm, I was going down a hill that was totally frozen and led to an intersection. I was doing 10-15 mph, but that didn't matter. I braked hard, and the ABS did it's thing... but ABS or not, I would have just kept sliding through that intersection, which is what happened, because I lost all traction completely. Fortunately, the only oncoming car was doing about 25 mph and was a hundred meters or more away, so I got away unscathed.
ABS is a huge plus. If you've ever tried to threshold brake in a car with conventional brakes, then you realize how much work ABS is doing for you. Insurance companies will give you a discount for having ABS.
