I cannot see how you couldn't ride a rear steering bike as easily as a front steering bike remembering that you do not turn the wheel much and that would be a handicap since you couldn't determine how much you were turning the rear wheel by sight.

If you did some reading on the "rear wheel steering" attempts people
have made for decades, and the very limited success they've had, you
might change your mind.

If rear wheel steering were easy, almost every recumbent would use it
because of the simpler and more compact drive train.

Just wondering if rear wheel steering would be easier if it was the FIRST method of riding a bicycle a person learned? That is like the almost unsteerable bike I linked to above, is it the learned behaviour of riding a normal steering bicycle that makes it so hard to ride a rear steering bicycle? Would a person who has never ridden a bicycle find a rear steering one so difficult?
