Having lived in Singapore and having had a Singapore PR for awhile? (Albeit awhile ago)
The reason why people own cars is for flexibility and to have some more control over their lives. Which is also a status symbol. It’s also really, really helpful with kids.
Is it still doable with public transit? Yes. And Singapore is easily one of the more pleasant and doable on that front. But it’s also a lot of dealing with crowds, taking time walking (while carrying things) or just not going, having to fit within society, and often having unpleasantness shoved in your face (well, as much as Singapore has anyway, which isn’t a lot) from society as part of the normal routine.
Unlike Paris, SF, NYC, at least you won’t have too many buskers and scam artists messing with you, which is nice.
If you get in a car, due to all the costs and taxes, the experience is generally a more quiet and pleasant one, and you can go anywhere on the island with (less) worry about what loud/raucous/unpleasant mess you might be stuck being near. And if you do get stuck somewhere, as long as you have AC, you can roll up the windows and mostly ignore any shitshow going on. Which is nice.
Compared to NYC, Paris, SF, Seattle on my list of ‘ugh’ places with public transit), it’s not on the bad list at all.
When I lived there, it was about as good as Switzerland or Tokyo with how well it was run (you’re welcome PAP), but obviously a different cultural feel.
Unlike Switzerland, you do have the more Chinese influenced ‘everyone’s business is my business’, especially from the Ajimas.
And if you’re a Gwailo, you’ll stick out like a sore thumb everywhere - and everyone DOES notice - which has pros and cons.
Also, no worries about folks bringing Durian onboard in Zurich for instance.
I didn’t even try Indian public transit, but that’s my loss I guess. It was sketchy enough just using cabs.
Driving in India is an invitation to get scammed and/or ruined on its own, so
I can’t imagine wading through the crowds. That said, the scams tend to be less in your face than in the western societies, and the scammers more subtle and far less violent. Which is nice, I guess?
Germany, Spain, and UK have good public transit, and middle of the pack for pleasantness.
The Danes run decent public transit in the big cities, but the lack of density meant you could easily be stuck somewhere (and have a very long, very cold walk) if you didn’t know the local holiday schedule. And they didn’t do much signage to tell you.
If done well, Public Transit can be very effective and definitely reduces cost and load with having a vehicle.
But it’s not a place for quiet contemplation (except perhaps in Switzerland, but even then it depends on the day), and it means you’re always dependent on the society you’re in and have to know how it works (and when) to get anywhere.
Which can be limiting in a way Americans outside the cities are used to not being limited.
Also, there is a reason New Yorkers are known for being in your face assholes. You would too - or be crushed - if you had to deal with the people in their daily life that they do.
