Sort of like an exponential acceleration curve? That's interesting and it would approximate type ICE acceleration at certain speeds. One benefit of exponential acceleration is that you would get an extra push at top speeds that could help making a lane pass for example. I like it.

BTW, I keep going back to the weight factor of standard industrial motors. There are some real gems out there in terms of specs: 50 HP, vector rated, 220/460 V, 90% efficiency, $1500 shipped... but then weight is 700 lbs.
