It also states that the car will "freewheel" when you let off the gas, which means that the clutch is disengaging, which means the throwout bearing and thrust bearing are getting a massive workout, which means they will fail prematurely. Far earlier than they should, anyway.
Also, there's nothing mentioned about release speed, or how it's controlled. So what about when you want an easy takeoff, but then you want to have some fun and do a burnout, or launch the car? How does it know what you want to do?
Lots of issues I can think of.
