The sad truth is the USA spends ~$150B/year building and maintaining it's road network (to say nothing of the inflation-adjusted costs that went into its initial roll-out). Source: The US Fed tracks it directly - https://fred.stlouisfed.org/series/TLHWYCONS

That's a $41/month subscription every citizen's paying no matter what. When we're pulling cash on that volume from everyone's pockets to build lavish infrastructure literally up to people's doors (vastly more road square footage than housing+school square footage combined), of course folks are going to say "nothing compares" -- because nothing does compare. Which stinks (imagine if we'd focused a century of spending on rail at rates like that; damn), but it is what we have at the moment.

Seems like a bargain by comparison! Chicago is about to spend $1 billion/mile to extend an above-ground train line: https://en.wikipedia.org/wiki/Red_Line_Extension
