Think about it a minute.
Men use wheelbarrows. Hand trucks. Chainsaws.
All require two hands out front.
Hitching a horse to ride. Holding reins to plow with a mule.
You kind of hold the reins on a pinball machine after hitching yourself to it.
Riding a motorcycle. Controls on the right and left, steering it with nudges.
I think this is an evolutionary thing, even though I don't believe in evolution.
Carry on!
