> Cars reduce noise compared to subways squealing and rattling, compared to commuter rail horns blasting, and compared to the big engines of diesel buses.

As a US citizen living in Germany, I have to disagree. I live one very quiet residential block from a nationwide major rail artery and do not hear or feel the trains. Noisy, squeaky, rattling, rail horn blasting trains are a choice made by underfunded, weak, and poorly organized governments and transportation organizations. In the US, it is only that way because the US has chosen to prioritize cars over all other means of transportation.
