Stop distance, shmop distance.
The actual brake distance to 0 isn't as important as many seem to think. When did you see an accident where the vehicle failed to come to a full stop, not counting fender-benders by tailgating idiots?
What's more important is the ability to steer well while decelerating. That way you don't get that fender-bender because you were tailgating, as you can avoid the vehicle that stopped. And you avoid the risk of some of the more serious accidents too, like hitting an oncoming vehicle (or a tree!) dead on because panic braking reduced steerability.
