errmm.. is that not what the old mechanical 'training wheels' pretty much do? They seem to help plenty of kids learn to ride.

Anyways, Ithink you are taking this way too seriously, in my opinion. So long as people dont use them in competition where rules forbid it, why should you care if one uses this product..

Seems if there was a way to dial down the sensitivity gradually as you learn (may very well have, Idont know), that would be very similar to training wheels, would it not?
