I'm more likely to believe you than some. Is this really possible?

I'd want to stick the motors _and_ the brakes inboard on drive shafts.
But I know I'm old fashioned...

Apart from unsprung weight, the motors are subjected to all the shocks
from bumps/potholes etc. and water.
Only part of driveshafts contributes to unsprung weight.

Motor in hubs are available as a DIY hybrid conversion, ie you take a
normal car and add the batteries and motorised hubs.
