Think: Freight train stoppage.
There is a whole lotta friction during the best of times without asserting the brakes. Look how long they take to stop these not-so-light long bricks-in-the-wind even with ALL brakes asserted (a very long distance).
Well, yes in that case....but if you had a "bike" with skinny hard wheels and you disconnected the chain, and you towed it up to 40 mph, it would potentially go as far or farther than a car if you reduced friction enough. The main point is it's the relative ratio of friction and mass. A hockey puck on ice may travel farther than a car coasting on ice given the same starting speed (see...I brought it down to a level that you Canadians can grok)
Heh, heh, ... grok, ... I think I understand now.
