Question about the ending in the car
I really liked this movie.
But a while after watching it, I wondered about them not hot wiring the car.
I know they didn't do it because they didn't want to screw up the wiring as they had before in other cars.
However, IMHO it was worth another try.
Also, I have a little experience with ignitions. Basically, they could have knocked the plastic casing off the steering column, smashed off the piece where you put the key in, and jammed a flat head screw driver in with their baseball bat.
Turn the screw driver and voila, the car starts.
I thought, that in their desperation, they might try and exhaust every last ounce of creativity in order to get out of the situation.
