As for the specific solution you suggested, I think that sounds great, although it isn’t obvious to me that it would “cost nothing”. At the very least, deciding on parking spots for them seems like it would take a lot of a bunch of government employees’ time. It certainly seems reasonable to me to start with a permitting system on the handful of companies, which seems like it would take much less time to implement.
This is why I hate the things.
Because when your only hammer is regulation everything else is a nail.
Edit: this isn't meant negatively. If you ask a painter what will make your house nicer they'll tell you to paint it. If you ask an organization that creates and enforces legislation to solve a problem they'll try to legislate it out of existence. Problems are solved with the tools at hand.
PS: A much better solution IMO is to simply pick them up and sell em for scrap. Problem solved.
Let's just say that I disagree.
Sure, ideally, the scooter company should pay some kind of tax or fee to help pay for the infrastructure, but I'm not convinced that it needs to be a special tax or fee, applied only to the scooter companies, beyond typical general corporate income taxes etc. that the scooter company is already paying. Particularly because the infrastructure costs involved are cheap. In my opinion, society is better served by government moving quickly to provide needed services out of a general fund, than it is by delaying action for months or years just so that expenditures are 100% just instead of 99.9999% just. There is a balance...
The answer (supposedly) is due to widespread anti-littering campaigns and the new ubiquity of trash cans. Why can't there be similar measures for scooters? Painting lines on sidewalks saying "it's OK to park a scooter here!" (painting lines being an option that costs almost nothing and is completed extremely quickly) combined with signage saying "you must park dockless scooters only in the lines or else $250 fine" (akin to only throwing trash in trash bins or else fine).
Scooters aren't inherently problematic, it's the sclerotic municipalities which refuse to adapt to changing circumstances who are the real culprits.
