People who work together and live even remotely close should be car pooling. There's no reason to pay 2 or 3x as much for gas if you could share the ride. Same goes for college students who live close. Buy one parking pass and share the ride with someone. Yeah fuel is getting higher and higher, but you have the power to cut that bill completely in half or even by 2/3 if you had 3 people to carpool with.
