Note that the UK's new high speed rail (HS2) is budgeted at £33bn ($51bn) and likely to exceed that[0]. Being mostly straight, and across land already approved for rail use, it seems like an ideal candidate for a hyperloop alternative. At 120 miles long[1] compared to the SF<->LA ~350 miles, a UK hyperloop would be even cheaper, especially since the major cost is the tube itself. A back of the envelope calculation[2] gives a cost of about £1.9bn ($2.9bn) which is suspiciously, almost absurdly, cheap. If anyone can find any flaws in this argument (specifically related to e.g. UK-specific issues/laws that I may be unaware of) I'd be very interested to hear them!
