I posted at the same time as bennelson - and now I have a comment on his post as well!

Ben - I thought about something like this, but only using a sort of gear selector for the "speeds" making it seem more like driving a ICE car....

In a manual transmission, 1st gear might be 12VDC, 2nd 18VDC, 3rd, 24VDC, 4th 30VDC, 5th 36VDC (not specifically those voltages, but constantly having a (X number) of amps, still limited by pedal/controller, regardless of number/configuration of batteries.)

It seems like an enormous waste of time though, other than being able to choose your speed/range more accurately than just pushing a pedal...

Sound like something worthwhile?
