Conservatively estimating the US has spent around $20T on cars, fuel for cars and car related infrastructure, mostly on fuel for cars which only contributes to (making the car move, drill baby drill, and pollution (used to be lead pollution too) )
A similar estimate, but over a longer period of time puts trains at $2T, their fuel nowadays is electricity, which can be clean, but also creates infrastructure that contributes to society.

This estimate doesn't include private capital (aside from buying passes/tickets/gas, but I can assure you that it only puts the gap MUCH wider)

Isn't it time we give up on the frankly silly idea that everyone needs their own personal asphalt eating tank? I'm not saying you have to live in the city, i'm just saying a tram (for the disabled) to the market from a suburb or a simple direct, tree covered, bike way is more than enough.
