If Hertz or Avis attempted to use public space to park their inventory, local residents and city officials would pitch a fit. Public parking exists for the benefit of the public at large, not as a cost-saving measure for rental firms. The same is true of bicycles. You can store your private bicycle almost anywhere you like in public. But city fathers will naturally take a dim view of a business using that public spac…
This is the point under contention. I strongy disagree, I would very happily give up public parking for other uses of that space - more bike/scooter lanes that can be further offset from fast-moving cars, dedicated space for Uber/Lyft dropoffs that don't block the roads, 5-minute loading/unloading parking for Fedex trucks and Postmates delivery people to idle for a few minutes.
Free (or heavily subsidized) parking for private cars is at the bottom of this list for me. It's also much more expensive to provide than these other things, because there's only one person benefitting from each parking space per few hours while all the others can benefit many more people. And even for the very drivers that street parking is intended to benefit - in lots of situations there are too few spaces on the street at all, so we're blocking this valuable space and most people won't find a spot anyway and will be forced to use a private garage.
And it's not that I never drive, I sometimes do, I still think it's a much better use of public space if I had to find a private lot or garage on the occasions when I drive so that these other things can be available to everyone.
