There was a study a while back that showed that the USA has eight times as many parking spaces as it has cars. At first that seems crazy, but it makes sense if you think about the fact that all the places you go in a day need to have enough parking to meet their peak demand all year, so places like malls have huge empty lots most of the year until Christmas rolls around. And then there is the spot your car is in at w…
I think we wouldn't see things as being nearly this bad if all American cities didn't rip out their tram networks. Every city I've lived in, even small ones with ~100k people, use to have Streetcars. Today, cities like Cincinnati struggle to get a tiny segment put in. Trams carry a ton more people than buses. People are more likely to ride them too. If American cities hadn't given in to GM and Ford and kept streetcar…
Busses use much more of the existing infrastructure, which is one of the main reasons cities struggle to get a tiny segment put in. Busses are also much more adjustable to the city's needs. You can increase and decrease frequency on routs - or change routes by moving stops. Construction? Adjust routes. One bus down? Off the the mechanic and replace it with one of the backups.
And I'm not sure that would have helped parking and car ownership in the US. For some time, part of the dream was to own a car. A car meant freedom and it often still does as the us, as a whole, lacks decent public transportation outside of the larger cities. Sometimes the busses are stopped before the bars close, for example. Traveling from city to city? Good luck or prepare to be majorly inconvenienced. (overnight layovers, for example).
