My grandfather had two habits drilled into him in the Army: never put your hands in your pockets so they’re always ready for action, and always park your vehicle so it’s ready to go.
This means he always backed in, and always parked as close to the exit as possible. And he did post-drive checks to ensure fluids, lights, brakes etc. were as they should be and the vehicle was ready for immediate use.
And he wasn’t even a getaway driver after the war.
