Some ABS systems have kept cars from stopping in time.
A poor reason not to have it. Usually it’s better to keep the wheels from locking up, thus preserving the ability to steer. Granted, wheel lockup may stop you (straight line) a bit shorter than with ABS, but more often it’s better to be able to steer out of trouble. ABS is safety equipment that is a plus most (but not all) of the time. Just as seat belts or air bags can kill you once in a while – should we get rid of them on the off chance that they’ll do that?
