I think it is regulatory. However getting US politicians to do what’s right is never trivial. It would take the legislative branch to change the regulations, while likely ignoring lobbyists within the automotive industry. It’s fixable but it won’t be fixed.
Rental companies, at least in America, have policies against using their vehicles to tow things.
In addition the truck in front has to be imported to the US and there’s weird regulations about purchasing them so you can only buy used. As far as I know you can’t import a new model. If a car is newer than 25 years old it can not be imported unless it meets the requirements of US Office of Vehicle Safety Compliance.
