Making tunnels for robocars would be vastly cheaper than subways for trains like SF's new Central Subway
Submitted by brad on Mon, 2018-03-05 12:42San Francisco is building its new Central Subway -- an underground light rail line. Ground was broken in 2010 but due to delays it will not open until 2021. This line will finally make the Caltrain commuter rail (which otherwise dumps passengers into an industrial zone far from where most of them wish to go) more useful, and offer travel not slowed by SF's terrible central district congestion.
