Yea, and it took 80 years and three generations to get to your destination.
It depends how far back you want to go, but it absolutely was true.
Ignoring that fact, everything is designed around car transportation. You can’t just kill that off in any reasonable amount of time with a different solution. You’re talking no less than 50+ years if that is the main focus, ignoring all of the other much more significant issues. Rails don’t just pop-up. Rural living residents and small townships aren’t just gonna up and leave. Cars are here to stay, the best you can hope for is better public transport, some functional rails, and realistically, more efficient vehicles. Welcome to reality.
If that’s true, and it’s going to take 50+ years, shouldn’t we start, like, now?
We don’t have 50 years. As Bill Nye said, the planet’s on fucking fire. Emit less carbon, motherfuckers.
