- Sure. Your argument is that the wheels can't have a sideways motion component
- because the sticky tires are glued to the ground. Well, you're right, they
- don't slide to the side, but they can roll that way (roll right out from
- under you) and they do. The reason your student slid was because he initiated
- this sideways component too quickly, and the wheels could not roll that way
- fast enough (this is just one of many ways of looking at the phenomenon) and
- the force was strong enough to break traction. But please, don't take my
- word for it, get out on the road and try it (not the sliding part).

- I got the cc's from Ed's reply, & CP's reply back, but I thought that I'd
- add my two cents anyway.
