Yeah electric motors like to spin at much higher RPMs than piston engines.

When you are stopped idealy your motor RPMs should be 0. To keep an auto transmission operating "smoothly" you will need to keep the motor around 500 or more RPMs to make transitioning between stop and go nice and smooth.

Why pick the most difficult setup possible?
Transsitioning from 0 RPMs @ 0 MPH to slow speed with an AC motor and auto transmission would be the most difficult combo I could think of.
Where a DC motor on a standard transmission with clutch and fly wheel would be smooth/easy/cheap.

It would be like my camaro many years ago before I knew how to tune the carb. At one point when the tachometer wasn't working the idle speed slowly drifted down to about 300 RPMs over time. When I was stopped and started to press the gas to go again the car would jerk forward as the torque converter hit stall speed.

If you are looking for a easy to build smooth running setup, this ain't it.
