As far as the mesira aspect, it’s clear in the רמ”א in שפ”ח י”ב that it wouldn’t be an issue here (again, specifically where he’s blocking access and caling the police and the tow truck will get his car out ire quickly).
The value of his car is surely more than the ticket and towing fees, so if you’re allowed al pi halacha to smash his car if there’s no other way, you’re certainly allowed to cause him a smaller loss.
