Sure, it's capital intensive. But that goes for all necessary infrastructure in dense, urban areas.

Shit needs to be channeled away and cleaned, electricity and networks need to be provided, water has to be served, etc.

Public transport is not different. And calculated on the amount of people it serves I'd argue that it's cheaper than cars. Especially if the externalities are factored in.

I'm not saying that scooters can't add something to the mix if done right. But the situation - as is - is not as bad as you make it out. Especially for cities that do it right.

Do you have an example of mass transit 'done right' in a city in the US?

Seems to me that scooters (or bikeshares etc) are highly complementary to mass transit, since you're never going to get rail lines everywhere.

Caltrain from SF-SV works well, but it's far from cheap anymore. Round trip from Sunnyvale (Lawrence) to SF, for example, is over $20 now.

Roads are way more expensive to maintain than a track, which is why rail is cheaper than road shipping costs.

Cities that aren’t big at all like Bern really show off the advantage of mass transit infrastructure.
