Think of it as doing a parallel turn on an ice rink but on roller skates. You'll stop eventually but 9/10 times you'll land on your ass, but you will stop quicker than just skating on by!
With all respect, I disagree. Nobody will be dumped to his a$$ by a surprise stop! :)
It's rather like snowplough, known from skiing => coming to a halt eventually.
