>>1897348HSR but not retarded non-stop NY to LA lines.
rune them on hub and spokes, with large cities branching to other large cities with spokes to medium cities.
Also tunnel interstates under cities, not through them. If you need to get off, get off before you go under, otherwise it's just for thru-traffic.
Add in trams and metro lines that reach large suburbs bordering the city to help suburbanites reach the interior where the HSR stations are, and you got 80% of the nation connected.
As for the HSR cost, the feds already own the green in pic-related. Most overpasses are due for replacement, so stone two birds at once.
>cars are still legal>bike lanes are still maintained>interstates are actually preserved with new HSR lines, so cars are allowed to continue use in the future
