I mean I like bashing on Tesla as much as the next guy, but any car can end up like this regardless of price. They probably bumped into something that broke the locking mechanism and this is probably just a temporary solution until they get it replaced.
Yeah buddy of mine mended his lease car with duct tape. He rear-ended someone at a roundabout at 30 km/h. Couldn't get it fixed quickly, had to wait 3 months for the garage.
