Yes it was bad engineering. The goal was to tell us position on the field not distances. To give us range I would have used ultrasonic sensors.

Yes, mounting an encoder so that it gets the least RPMs is a good idea but sometimes even that is a high number. Say, for shooter wheels in 2006. Yes an encoder could tell you the speed but running constantly at high RPMs just doesn't seem like a good idea to me.
