At least the Soviet Union/Russia had/has an incredible public transport system. (Gorgeous subway.)
CA has NONE of that. NONE. It’s so not set up for anything collective.
Trump literally JUST cancelled the *FAILED* CA high speed railway project.
Most of those subways in Moscow, at least, serve a couple purposes.
In many stations, they have hidden blast doors. There is also hidden storage. They have special ventilation.
They are very deep underground.
They were built for public transportation and nuclear war.
