Given the proliferation of microtransit services trying to match drivers and passengers, you might think they had ride-sharing and carpooling all figured out. But the recent demise of Leap Transit in San Francisco—to say nothing of the other transportation start-ups that have failed without a media whimper—reminds us that even in a big city it’s not easy to fill empty vehicle seats. And in the suburbs, it’s downright mathematically impossible.

Or just about, anyway, according to a provocative new thought-experiment by Steve Raney, principal at a smart mobility consultancy called Cities21. In a working paper, the former Silicon Valley tech product manager crunched the numbers on ride-sharing in the Palo Alto area and found the odds of matching drivers with passengers long, to say the least. Raney calls it the “Suburban Ridematch Needle in the Haystack Problem.”

“I wanted to gently inject some reality into this,” he tells CityLab.

    Private ownership of houses and land is very common in the USA; that includes cities. Often you have to look hard for rental property. You cannot maintain an owned house without at very least having a personal car (better, a truck.) Bags with salt for the water softener, bags of soil for the backyard, buckets of chlorine tablets for the pool, 10' lengths of PVC pipe for irrigation... all that cannot be delivered on a bus. In the UK cans of paint cannot be transported in public buses "for health and safety reasons."

    European population is significantly urbanized. Perhaps someone from EU can extend this comment from the other side of the ocean and give their side of the story - how common privately owned homes are, and what it takes to maintain them. Obviously, if you live in a rental apartment then all your maintenance duties consist of vacuum-cleaning the house.

    Private ownership of property is very common in the UK. Most houses are owned by the occupiers (though usually mortgaged), and a high proportion of flats [apartments] are leasehold where the occupier owns the occupancy (more or less indefinitely - like 99 or even 999 years) while the landlord maintains the outside for a "ground rent". I believe ownership is much less common in Germany and Eastern Europe though.

    then all your maintenance duties consist of vacuum-cleaning the house

    Thta's meant as a joke? The tenant is usually responsible for interior decoration and maintenance - which he must do. The whole rental thing is a Pandora's box of issues, and there are nearly wall-to-wall TV documentaries on it, with titles like "Landlords from Hell" and indeed "Tenants from Hell". A high proportion of landlords are crooks and extortionists.

    None of which has anything to do with car sharing.
