An open diff rear is not one wheel drive. Its either two wheel drive or zero wheel drive. If you have traction both tires put equal power to the ground. If you break one free neither tire puts power to the ground so its zero wheel drive
Sorry, but you're incorrect. Get stuck with an open dif and see how may tires turn. I guarantee you it won't be two or zero.
Or ...
Do a burn out with an open dif and see many tracks it leaves.
No, you are incorrect again. I am well aware that in an open differential when one tire loses traction it spins, and you dont go anywhere.
You are confusing yourself by seeing that one tire spin. One tire spinning with no traction does not equal power to the ground and does not equal one wheel drive. An open differential applies essentially equal power to the ground through both tires. Either both tires apply power to the ground or neither do. If one tire spins due to loss of traction, neither tire is putting power to the ground and that equals zero drive.
