Logically, you can see the reasoning behind things like "wipe off 5". If you have an accident at 105kph, you will hit an object more than 5kph faster than if you were doing just 100 when you reacted...simple Newtonian physics. However, if you were only doing 95, you would have hit at an even slower speed. And take another 5 off you may even avoid the accident. Applying the logic of "but if you were driving slower, you may not have an accident" has a natural conclusion of travelling at zero velocity means you won't hit anything...you may still GET hit though.
The statement may be logical, and even self evident, but the ultimate conclusion is ludicrous...every one should drive at a velocity of zero.
