What? Are you serious??? If it's true then in US you are getting ripped off big time. The whole crossrail project is 73 miles with 14 miles of tunnels and 40 station and it has a cost of 15B£ (19B$ with today exchange rate). I cannot find the total cost of the tunnels, but apparently for 1.25B£ you can have 18km of tunnels: http://www.crossrail.co.uk/news/articles/crossrail-awards-ma... That is 1.6B$ for 11 miles. Basically an order of magnitude less than your figure of 1B$ per mile. If really Musk wants to improve by an order of magnitude over that figure then he is late, the crossrail tunnel have been completed 2 years ago.
Those Crossrail numbers give $0.2B/mile, including a lot of miles of track that aren't tunnels. After digging a bit I found this, which is a good summary:

It seems that $1B/__km__ (not mile, you're right) is sadly par for the course in the US, and Crossrail passes that threshold too. Projects elsewhere are below that threshold though.
No the total number include the tunnels, the tracks outside and 40 (FORTY) underground stations. The specific figure of 1.25B£ is taken from the official documents for 18km of tunnels alone. So do you think that an unknown blog that throws some figures without any reference must be more accurate than the official figures, reported in public documents accessible to everyone, that explicitly says that 18km of tunnels ALONE have been built for 1.25B£. Next are you going to post a link from some chem-trails website?
No need to get stroppy, calm down.
