My guess is that a lot of this is a protest, and has to do with people being unhappy with either scooter parking, or people riding the scooters, or perhaps the fees charged by the scooter companies.
The companies need to start a PR campaign, and some method to police bad riders.
And, of course, allowing the scooters into a riverfront park doesn't help.
Nonetheless, it may well be a half mile stretch of bike path that needs to be monitored. Do the scooter companies have the locations and times when the scooters went offline?
Damage and replacement costs may be higher than the vandals expect, and could land them in a fair amount of hot water if caught.
