They also make a reversing contactor so you can use 1st - 3rd backwards too. But that costs a couple hundred for a good one, and the whole car costs like $800. What sort of efficiency gain from less rotating mass would you get from just keeping 1st - 3rd (or in my case, just 1st and 2nd)? Normally a transmission/driveTrain is like 90% efficient, right? Could you bring it up to 95%? That's a very interesting idea, Jesus.
