Re: Mass transit works best in densely populated areas
Singapore is an interesting example...
A city state with limited space. They charge a toll for every vehicle entering the city centre. The toll is high. They also charge a tax on owning a car at all. That tax is extremely high.
The result? The rich still ostentatiously drive big cars, but most people use public transport, because the public system is directly subsidised from the tolls.
The metro is incredibly cheap (less than a stick of gum), and fast and clean - and safe.
Buses are also remarkably good compared to those you and I know.
Unfortunately, most governments are too greedy to give money back to the sector it is earned in, so this doesn't work worldwide.
[What % of your gasoline tax is paid back in road funding, for example?]
