"NEXT STOP: LIBERAL AGENDA STATION!"
But in the city ...
Drive a car in a city and you'll spend every moment on the the road imagining yourself killing each family member represented by the stickers on the back of every SUV. In time, your state of mind will take a turn for the decidedly homicidal since driving in and around cities is so hellish and enraging it can literally takes years off your life.
The inefficiency of it all will make you want to drive into the nearest body of water, if only you weren't in the middle of gridlock. But then, the light bulb over your head flickers to life: What if there were some sort of mass public transportation many could use at once?
Even if you decide you don't want to deal with other people's weird smells and incessant throat clearing, your drive to work would still take half the time because of all the phlegmy, weird-smelling people who took the train instead.
At least in your car, the breakfast burrito farts you're inhaling are your own.
Public transportation forces you into a tube on wheels with people of every race and religion and makes it a part of your daily routine.
Congratulations -- you've taken your first step toward becoming a member of the "liberal elite." And it had nothing to do with "going green."
