Corrected entry: When Baby is in his boss' car, the boss puts both hands on the steering wheel, and then the sound of the car's engine starting can be heard. He could not have turned the key/ pushed the button with both hands on the steering wheel.

Correction: The scene you are suggesting simply did not happen in the movie. Please watch it again and you will see Baby start the car with the button before doing anything else.
