Skipping ABS and ESC is a mistake. They're essentially standard, save thousands of lives per year, and ESC is already mandatory in the EU. Having an efficient electric motor requires a computer controlling it. A standard ESC (VSI topology) is an indirect command on its own and the power depends on transient conditions. The controller doesn't know much about the motor and doesn't account for nonlinearities that cause loss under acceleration. The driving experience is the same as a subway train. To run a motor at maximum efficiency under all load conditions you need a computer in the loop, running vector/field-oriented/direct-torque control or something similar. It's not an insignificant loss otherwise, particularly with induction motors. It's also a flat-out requirement for some of the best motors- the EV industry is moving towards permanent magnet assisted reluctance motors, which are ~10% efficient without computer control.
