>Good for a party trick but in general I have yet to find a good real use case for it.
It's particularly hilarious when you and several buddies are watching the meter maid try to put a ticket on it. It's probably occasionally useful for adjusting a car in the driveway but yeah, it's 99% party trick.
It could theoretically be useful for attaching a trailer but most Tesla owners aren't doing that and the collision detection system will probably go crazy and prevent you from getting close enough to the trailer to actually couple it to the car.
