Yes, I perfectly see where you're coming from and pray for the expansion of public transit and stepping away from the concept of "well, they fit in" as a metric of capacity.
People should be able to move around with comfort, not wait for ages for their bus to arrive only to be crammed in. There should be more comforts in general, more secluded spaces, better planning, seats for everyone.
Part of me wonders what our public transit system would look like if we could actually put all the money we buy cars on and directly use it to develop public options. We could quite literally build our transportation from goddamn gold should we want to for whatever reason. But that's daydreaming.
Until then...happy driving!
