I live in Switzerland, it doesn't get more developed re infrastructure on country level than this really. Car ownership ain't going away, train network is fine but a) ridiculously expensive and prices are raising each year; b) certainly not good enough for many many tasks, unless you like spending 2h in trains/buses instead of 30 mins in the car, sometimes there is just nothing.
Yes you can arrange your life and simply experience less, but why the heck would anybody do that? Private car ownership is at all time high and not slowing down, there are visibly more and more cars on the roads every year.
Self-driving may change that, once it comes. I estimate 2040 earliest en masse, musk poisoned that pond pretty badly with his lies and unfulfilled promises. It just became a no-topic for next decade and some.
I live in Seoul where despite its jokingly small size, people have car(s). We already have highspeed rails and everything. Cars are definitely not going anywhere unless specifically went against it by governemntal policies.
This would cost £1.92 in my EV (or £7.68 in my old diesel).
It would also cost me £1.92 for my whole family in the same car, whereas the train fair would multiply.
There’s a lot more to it than that of course but public transport is expensive.
