Firstly. Within 5 minutes you can edit the original post and
no one will even know.
Secondly, 36 posts since 2010? Have a couple thanks for posting.
More to the point. A computer isn't strictly required, but I'm not sure that's the question. Consider a through-the-road hybrid. Thanks for offering the Baja Bug as an example. I've got one on jack-stands in a barn.
A through-the-road hybrid could have a VW/Subaru rear-wheel drive, and electric front hubs under driver control, e.g. with a one or two lever 'cutting brake' that instead of being in the hydraulic system would provide
command to the electric
controller.
The link-pin front hubs could be substituted with Schwimmwagen hubs, else the front brakes could be substituted with electric drive/regen hubs.
Don't get me started....
Edit: With single-lever regen, you could use the regen as a brake while you warm up the rear tires.
