Correct me if I'm wrong but, if I understand things correctly... at this point we're wondering if manual locking hubs are a better (or worse) solution than electrically isolating the motor(s). Right?

And, off the top of my head I'm going to say the manual locking hubs will be better overall. Better from an energy efficiency perspective as well as overall convenience and simplicity of design. They might be worse for Tesla's P&L though since anyone with a tire jack and a standard parts dealer nearby could work on the car.

Then again, besides the fact that I'm a cynic... what the heck do I really know!??!

I don't think it would be useful for me to speculate about that. I'm just attempting to clear up some apparent misunderstandings about regenerative braking.
