Presumably because parking brakes are merely a suggestion (particularly on a hilly driveway), these are multiple security camera angles of a man chasing a car that’s trying to make a getaway while he washes a BMW, successfully nose-diving over over an embankment before he’s able to stop it. On the up side, at least it wasn’t the more expensive of the two that decided to take itself for a joyride. Or maybe this one was sad he was giving the BMW a wash instead of it and jealousy drove it to madness. Or, who knows, maybe it’s just a car and doesn’t have feelings. That’s total bullshit though if Optimus Prime taught me anything.
Keep going for all angles, including the tow truck rescuing the car.
