They already have those. They're called Walmart parking lots and the arrangement is mutually beneficial. Walmart gets security, people get a place to park and sleep for free without being hassled by cops. I understand that people who live in "nice places" may be skeptical of their existence but trust me, they exist.

"Nice places" with Walmart usually make the existence of said Walmart conditional on that particular store not allowing overnight parking.

Walmart parking lots pale in comparison to what I'm suggesting. If you are a Google employee already, a Google parking lot is pretty darn good but still not as good as what I'm suggesting.

Sure, if you are on a road-trip and in a pinch Walmart is OK. But if tied to a region, you can do much better than Walmart (as evidenced by driving around the valley and cities and seeing where the vans are parked).

RV parks have been around for a very long time.

I suppose it would be like RV parks in a superficial sense of vans parking and paying a fee. However, I would suggest catering to car/van dweller minimalists, that don't have the features of an RV, by offering high quality, useful amenities. I would also take inspiration from maker/hacker spaces for more value-added options.

Really maker-spaces or artist loft warehouses could fill most of the need if they had enough parking and tweaked some things.
