Build a small wagon with square wheels and push it along a road for one mile. You will notice that at the beginning that wagon will jerk up and down. After one mile you will notice that the jerking is less pronounced, and pushing the wagon forwards is easier.
A close at the wheels will reveil that the corners of the wheels got rounded.
After more miles the pushing gets easier and easier, until the wheel is completly round.
I got that idea from: *The Flying Sorcerers by David Gerrold& Larry Niven*
