What needs to happen first is fuel price needs to be so high that people are incentivized to
a) switch to public transit no matter how shitty it is because they just can’t afford a car anymore
b) start public transit companies because there is money to be made and the oil lobbies don’t have enough money anymore to lobby effectively
My guess is before 2050 nobody will really get anything done because the oil lobby is just too powerful. Would be great though.
