In a dense city like NYC, public transportation is the obvious choice. In a semi-dense city like Seattle, public transportation is a viable choice. In a nebulous agglomeration like LA, public transportation is hard to rely on.
Good thing LA is nicer than I used to think.
In places like London, to my limited knowledge public transport is the only valid choice for transportation, as car traffic is in constant jam, parking is impossible to find and costs a fortune.
Countries like Belgium and Netherlands are highly urbanised and from my experience it's the same story - you do not take a car to go to work (if you work in the city/downtown). People even have jobs that they have in different cities and they take express trains everyday.
I agree though that US's suburban and car-centric model, with endless cul-de-sacs is not designed to have public transport. To retrofit public transport into this - is a colossal task, though it's also an effort to change peoples minds, that not relying on a car is "an attack on freedom" and public transport is not only for poor people.
I've lived in two places with busses. One is my current location in Norway, and I don't need a car to do my everyday stuff. The other was in Indiana. You couldn't always get home if you worked second shift and you couldn't get home from the bar: they also didn't run on sundays.
Slightly more common were taxis (but I've lived more than one place without this as well). The taxis were never reliable in the US: For example, my car broke. I called the cab company, who told me that it was impossible to order a car ahead of time and they couldn't give me a decent time to call - waiting time could be anywhere from 15 minutes to two hours. As you can imagine, it makes getting to work or to a doctor appointment difficult - especially if you are stuck outside before they opened.
City to city public transportation just doesn't exist most places.
He's public transit truly been destroyed like that in many American cities?
