I'm going to hit a parked car and leave.
Why would you intentionally hit a parked car?
I just feel like messing with someone.
That's a really poor way to do it. You could cause significant damage, which you should pay for; imagine how the other driver will feel!
People take insurance to cover that kind of stuff.
Don't damage property. There's a good chance a camera will see you, there could even be one in the car.
