In case you haven’t seen any quonset huts for bicycles yet, here is one:
Those look strange, but maybe it helps against weathering and thievery.
I find those quonset huts great, so much better and more useful than parking lots for cars.
They also take up significantly less space per unit. I wonder how popular they’ll end up. Unfortunately, however, I don’t think anything will be able to take over the space needed for cars. At least here in America. In Europe, especially Germany, I can see automobiles being phased out for more economical and environmentally safe ways of travel. Such as bikes and the huge transit system in Germany. In my opinion, you never have to drive anywhere in Germany.
Gas is also, stupid expensive in Germany. So maybe that’ll be an incentive
