Carpool.

Whether to work, school, church, or fun, carpool as much as possible to save money on resources and to help the planet. Washington, D.C., has this hilarious concept called the slug lot. People pull up to the slug lot with 1 person in the vehicle, pick up a couple of travelers, and drive into town. These additional strangers qualify the vehicle to travel in the much faster high-occupancy lanes. D.C. also has a free ride home program in place in case you've come in with limited opportunities to get home and are in an emergency situation to return home (get sick midday). This helps to eliminate the qualms causing folks to avoid efficient community opportunities.
