The in-wheel swerve shifter!

When you drive on direction, power will be transmitted through set A while B free spins and vice versa.

Something I thought of that Aren Hill and I have been debating about for a while.

Interesting, and clever! That would be a good way to do it outside of a swerve or wheel, for something like a PTO. However, this way is a lot more compact if you are using it inside a wheel. Outside a wheel though, one-way bearings would do really well.
I always wondered, how do you get the one-way bearings to spin with the shaft though? Wouldn't the shaft just slip? Or do you add screw locker or something?
