Couldn't the scooter companies negotiate with businesses and get permission? Maybe pay businesses to install docking stations. The scooters get advertising when people see the station. The restaurant or hotel gets advertisment on the scooter app as a designated docking station. And the business can tow unwelcome scooters not in the dock. Just like they are allowed to tow cars.
Seems like the scooter startups think they're special and permits and regulations don't apply to them.
