>You could always invest in actual public transport & sane infrastructure, rather than relying on clogging the streets up with more cars, autonomous or otherwise

So what should the disabled people do until that amazing public transport infrastructure materializes, if it ever even does for them at all? Sit at home and wait?

I dislike this type of patronizing superficial handweaving advice that is disconnected from the harsh challenges of building more great public transport infra (lack of funds, geography and land ownership issues, nimbyism, public safety concerns, labor/material shortages, government bureaucracy, corruption and incompetence etc).

People use cars because they have no better choice. I'd also want my city to build me Swiss levels of public transport so I wouldn't have to drive, but guess what, the infra sucks and the city is insolvent, so that leaves me with little choice for the next decades as 100% nothing will change for the better in this regard, so then car driving it is. I didn't make it this way, it's the way the city management has botched it over the last decades, but it's still on me now to adapt to it, and cars are one of the ways.

I agree with you in spirit, that everyone should have great public transport ideally, but when cities are broke and that infra doesn't exist, then that externality is burdened on the individuals because they have no other choice but still need to get to work and other places. Telling them they can "just build more infra" is like telling homeless person they can just buy a house. OK cool, but with what money?

Public transport is not the same as cars. It's silly when people pretend like they are interchangeable and it's just a matter of having "better infrastructure".
