Power with Control
There is a reason that one can push the shifter from drive to neutral.. Along with one can reach forward and turn the key off to depower the engine.
This is true, and I agree everyone should have the technical knowledge of how to shut off any machine they operate, but "complex solutions" such as those are usually not counted. But what is this "key" that you speak of? Can I turn my fob to make the engine turn off? There are safeguards to prevent you from accidentally hitting the START button on the dash and killing the engine while at 70.
