I cannot think of a single other instance where something can be set up where if you don’t follow a rule while operating a vehicle, that actual damage to your property.
If illegally parked, sure, your car can be towed or booted, but not pushed down a hill out of the illegal parking space and into a wall.
If I’m missing something, someone please set me straight

May I offer an anecdote, which while not answering your question, may serve to illustrate your point?
(First, forgive me if this is not relevant, or constitutes a hi-jack, I am a newb here and am still learning the rules).
A long time ago, I drove 18-wheelers long-haul.
The Union 76 truckstop in Ontario, California was a haven for prostitutes, drug-dealers and parking lot muggers.
It was raided, deemed a nuisance and the management informed to clean it up or else.
They put a razor-wire topped concrete wall around the entire parking lot. (You had to buy fuel to get in). They had one of those “severe tire damage” apparatuses at the exit. They were retractable spikes that could only be crossed in one direction.
It was marked with a small sign. I witnessed a driver try to enter, there were several loud “booms”, and 8 of his tires were damaged beyond repair. I spoke with the driver, who had spoken to the manager, and he was SOL and had lost his job.
Is it legal? I think it might possibly be fought in small claims court.
Just like those gas pumps that have signs saying “Not responsible for fuel spills if automatic shut-off fails” Or those dump trucks that have signs saying “Keep 200 feet back! Not responsible for damage from flying debris”
Just because they post a sign does not make them free of responsibility. I know of several cases where people have gone to court and won.
