We already know what we need to do but people don’t want to do it.

That's the thing that gets me about AI solving global warming or whatever. You think a computer telling you that you have to get off oil is going to make a difference?

Soon it'snot going to be we don't want to do that it's we are going to have to.

Also if you look at happiness. We do want that some people don't know that, some don't know it's possible and some people have been outright lied to.

You're not wrong, but I don't really think society should bend too far to the whims of it's most antisocial members.

Like, if they don't want to share the bus with a black person they can leave. And I don't want to subsidize their selfishness by ceding space to cars, for example.

Also that's a bit of induced demand, probably. People drive because it's easier. Take away the subsidies or internalize the costs of driving, and people's habits will change.

Aerotaxis for the rich already exist: helicopters, Gulfstream, etc.

Or a 747 with everything inside gold plated if you're a Saudi Prince.

A century from now humanity's population will be lucky to number in the 6 digits.

Sure, but a public transportation system only vastly improves the lives of millions of people. How is that supposed to increase the bottom line of the car monopolists etc, eh? Nobody's thinking how their selfish demands of "a comfortable life for the majority of people", "a livable planet for future generations" or "letting the bottom 99% of the world's population have a little money too" affects the richest few individuals on the planet - they might have to refrain from buying another couple dozen yachts or villas each year! Won't somebody think of the poor, poor billionaires!

Driving itself is stressful for some people but I'm not sure how simply being in a self-driving car is worse than being on a bus. I can see how public transportation might be cheaper than a self-driving taxi but I don't see how it might be better if price isn't an issue. Why would someone prefer a method of transportation that (1) isn't directly door-to-door (2) runs on someone else's schedule (3) is often much slower than driving and (4) has to be shared with strangers over a method of transportation that has none of those disadvantages?

There are millions of families in Tokyo (and other cities too) who don't own a car, and manage to get their groceries without one.

It can be done.

But yeah it usually involves getting groceries more than once a week.

If we could rethink everything from scratch we could probably easily solve that use case.

Of course the hard part is changing from what we have now to whatever better solutions exist.

Like, things would be better if suburbia wasn't just an ocean of houses with sparse islands or shops. If every house was in a community with most of the basics reachable by foot... But how tf do we get to that?

You don't have to get a week's worth of groceries when you don't live in a car-first dystopia.

You walk five minutes to the store, spend 5-10 minutes grabbing stuff, then walk back with like a single bag. You shouldn't even need to get on public transit for basics like groceries, but even if you do a single bag isn't a problem.

Yeah, the solution to that is to have local groceries shops where you can go shopping on foot or just with a simply grocery cart walking less than 10 minutes. The idea that you have to haul several tonnes of food from 20+Km away is stupid.

Add: I find laughable how, whenever anyone makes this kind of comments, there comes out of the woodwork the whiny manbabys who assume that it argues for taking away their cars. Read again, never did I suggest to take anyone's car away, I'm making suggestions towards a better city, better living and better infrastructure. It says a lot that you're so openly willing to hurt and inconvenience others to defend against an entirely imaginary threat against your 2 ton toy. A car is a tool, not a personality. And if your personality is your car, I think you have a POS personality.
