Exactly. This sounds like a law and towing contract issue, not a disabled vehicle issue.
The tow companies likely wouldn't touch it after losing lawsuits in the past for damaging such a vehicle.
Mercedes-Benz in particular had an issue where after a collision, even a bumper tap, the car wouldn't start and would be locked in park. Tow companies quickly refused to tow them due to claims against them, which caused multiple instances of disabled Mercedes-Benz left blocking traffic.
I believe it was action on the part of states' attorneys general that forced Mercedes-Benz to change the programming in the car where a disabled vehicle could be taken out of park.
There are interviews with Elon Musk where it's shocking how much the engineers at Tesla had to learn after putting cars out on real roads in real situations. Watching the interviews is like being in a time machine listening to someone from the 1920s figuring it out for the first time. It shows they're amateur at best, deficient as a norm, commonly negligent, and criminal on occasion.
Not just any engineer is the solution
