Cars aren't the best option, but you can drop self-driving cars into an existing car-centric society one car at a time, with the car buyers paying for themselves.

Making a car-centric society meaningfully less car-centric requires the enthusiastic support of that society, along with competent political leadership, and probably a fair chunk of taxpayer cash too. Suburbs with huge lots make for long walks to the transit stop - but densifying those suburbs is not easy.

I don't own a car; I travel everywhere by bicycle and public transport - but the public transport I use was all built in the 1850s. Some time between then and now my society reorganised into a form that has a lot of difficulty delivering public transport projects.

This is a false alternative, because robocars do not exist, while public transit does exist but simply hasn’t been adequately implemented everywhere.

Politicians (and grifters alike) like to point to a future technology to solve an existing problem only to delay existing solutions which they don’t want to implement, most often for political reasons.

Robocars most certainly exist. They’re probably about 5% of car traffic in San Francisco. I’ve not taken one yet (taxis/ubers/Waymos are mostly impractical with a young kid in the US as you must use a car seat unlike in most European countries) but as a pedestrian they seem mostly a safer than other drivers. As a driver I expect they will eventually induce gridlock but the city can always create more bus lanes.

Portable booster seats are pretty small. I can’t see it working if you have a kid younger than the booster seat min though. Only a few states have strict rules here, Washington and California being a couple, although I think California has a taxi exemption.

Living in San Francisco I've not seen the taxi exemption for California anywhere. New York City taxis are exempt like most of Europe.

My kid is too young for a booster city. It's pretty impractical to take a child seat or booster with you unless you plan to hire a car the other end. When I travel back to see my family in Europe I take the train from the airport. So we bus and Bart to the airport even though it would be much easier with luggage to take a taxi.

Robotaxis ≠ robocars.

The robotaxis that do exist only do so in very limited places using very expensive technology (including off-shored service center for intervention) that is not available for the public consumer markets.

How old is your kid? In which European countries do you think the law does not mandate child seats ?

My kid is 2. New York City and most EU countries (including Spain, Portugal, UK, France) allow children to ride in taxis without a car seat.

This makes it far more practical for people to live without a car - hard to imagine in most of the US I know. As most such trips are low speed around town (e.g. getting to and from a train station or airport) it seems a reasonable trade off.

You of course need a car seat in a private car.

Oh, ok, in taxis you are right.

> robocars do not exist

How do you manage to discover Hacker News and not know Waymos are real? I'm truly fascinated by this new level of ignorance.

They mean consumer robocars as opposed to robotaxis. The latter exist, the former don't. And the latter are remotely controlled by operators when hard situations arise, but a blind consumer would presumably be on their own or would have to pay an additional subscription for that service.
