People don't own cars because they are cheaper. They own them for flexibility - which is why SUVs outsell compacts 10:1 despite worse gas mileage and higher prices. Competing solely on cost is a losing battle and has been since GM overtook ford in the '30s by offering style over pure function.

Cars are fashion, and convenience. Even if an uber was cheaper I wouldn't wait 5 minutes for one outside a store.

If you take an efficient autonomous ride share, you'd gain some conveniences:

No need to get a license, no need to do car registration, no need to insure your vehicle, no need to pay attention whilst driving, no need to find parking, no need to refuel/charge, no need to have the car maintained, no such thing as owning a car that has broken down, no need to change a busted tyre, and the list goes on.

You might need to wait a minute or two for the cheaper ride to arrive, though. Time will tell whether that's a bias based on our current context or a natural preference.

I get all those from the bus but people still don't take public transit. The wait is truly the killer - not cost.

You're right that people don't own cars because they are cheaper. But they will, in time, give up on car ownership because autonomous vehicles will be cheaper and better on other dimensions, too. Buses aren't a dedicated, direct ride to anywhere you want to go, so despite being cheaper, they don't stand in for car ownership.

Besides, with enough volume, an autonomous vehicle might pick you up faster from a store's exit faster than you can walk through a parking lot to your car.

I would definitely own my own personal autonomous vehicle. And I think the rest of America would as well. It's this vision of replacing ownership with autonomous taxi fleets that is not going to happen.

They are limited by roads and physics so they'll never have a wait time competitive with a car in the parking lot - and that is the killer.

I do see the allure on the economic side so I understand why this vision is being sold to VCs. But it's going to be just another feature the dealer tries to upsell you on.

When you exit a store, you can see other cars, right? Imagine if all of those were autonomous and able to pick you up.

Then they wouldn't be any cheaper than a car owned by me. The whole premise is they'd be cheaper from high utilization.

And if not cost what benefit does it have to take a taxi than my own self driving car? I can't leave my things in it. It won't have my radio stations set the way I want. And every trip I'm faced with the guilt of an explicit dollar value for the trip.
