Yes, public transportation is the "way to go" in order to keep city streets free-flowing and to reduce on automobile accidents and the injuries and death they cause. If everyone used a train or bus to get to and fro where they need to be, surely we would see a drop in needless death and injury.
If you have used public transportation you know it's limitations. It takes a significant portion of your day to get to and from some places. I think we should really beginning looking at phasing out gas powered engines in favor of electric. It's cleaner and environmentally friendly. We need to begin looking at the damage we are causing to this planet.
