Drunken Joan fumbles for the key to put in the lock of her Prius (unnecessary, if she had the fob with her, then the door would just open when she put her hand on it), then she gets in and sticks the key in the ignition (again, unnecessary), then she cranks the engine over (you just press the "on" button and the car is on in electric mode, so no engine cranking noise and no engine noise). Then she peels out - not too likely in a Prius, since for the first 5 or so mph the car is in electric mode.
