Try to make him do it while watching a 5 year old and an 8 year old while entering a car. It's a more realistic scenario for when you need a knob to work as expected.
There is so much more that we want to implement and some of it would give answers for your situation.
I think the Reality Editor will grow incremental and every version will be a bit better then the version before. In some years, when your car actually has this functionality, your scenario will be solved.
