Yes it does. http://www-nrd.nhtsa.dot.gov/vrtc/ca...99-01-1287.pdf "For most stopping maneuvers, made on most test surfaces, ABS-assisted panic stops were found to be shorter than those made with best effort or full pedal applications with the ABS disabled" Because people don't know how to brake. But the statement was overly simplistic, of course. ABS does not increase the power of the brakes, and does not increase the coefficient of friction. All it does is make it less likely that the driver will lock the wheels. With abs, if one wheel is about to lock, the other three wheels can remain braking. To avoid one wheel locking up with non-abs brakes, all four wheels have to stop braking. -- Cheers, Euan Gawnsoft: http://www.gawnsoft.co.sr Symbian/Epoc wiki: http://html.dnsalias.net:1122 Smalltalk links (harvested from comp.lang.smalltalk) http://html.dnsalias.net/gawnsoft/smalltalk |

But that's only relevant in specific conditions. I've already said it: ABS does not increase the braking performance of the car. It does compensate in some degree for poor technique, but even then you can fool it. Relying on ABS to "help you stop quicker" is stupid, and allowing people to think that's what it does is Not Smart. Guy -- May contain traces of irony.
