On the other hand, the benefits I get from that public transport are incredible - it's cheap, it's always there, it requires minimal logistics in groups (no trying to figure out who goes in what car and needs to be dropped off where at what time), it works regardless of my level of inebriation (admittedly I've not pushed that one to any sort of extreme yet), it's safe enough for children to travel independently (no dropping them off and picking them up), and it's largely accessible for people with difficulties walking or moving about.
I think a big part of the issue is that people have tried out poor public transport infrastructure and recognised - often correctly - that their car is way better for them. But good public infrastructure can often be far more convenient than cars, it just requires people to be motivated enough to build and finance it. A neighbour of mine didn't notice his car had been towed for a week because he used public transport so much and so rarely touched his car. When he'd parked his car it was fine, but then they needed to block of the street to do some work somewhere, and he didn't notice they'd confiscated all the cars there. That's the sort of effect that good public transport can have - so comfortable that you can forget you even have a car.
In order for someone else to have those benefits, they also need a car.
If as a society, if we could feel the same way about public transit, bike lanes, sidewalks, that you do about your own personal vehicle - we'd be better off.
It’s not like they’re the doctors guild that purposefully restricts the number of new doctors per year.
