Well, I guess we could all ride bikes. I guess we could start leaving for work an hour earlier every day. I guess we could not have ambulances and fire trucks. I guess we could not be allowed to travel as a family, unless we wanted to go back to the good old horse and buggy.
Y'know what? If everyone was on board for that, I bet I could get used to it. But I'm afraid the automobile has become a staple of standard human living. It gets us where we need to go in an incredibly convenient and comparatively quick manner. You find me a comparable benefit of smoking.
