Regarding "novice and expert" mode. Default should be novice mode. Extra steps to go into "expert" mode. Examples I could think of:
* Launch control (maximum acceleration from a stop.)
* Track mode (turn down or disable stability control)
* One pedal drive mode. (Nissan Leaf e-pedal or just B-mode for strong regen)
Ah well... It would be interesting to hear more of the reasons behind decisions.
