I know this isn't anything groundbreaking but I've been carpooling a lot recently and it's been really easy. The most frequent example of this is going from cross-country practice back home, instead of all driving separately from school to where we run, I and many of my teammates will drive in groups, and then carpool back to school where we are parked, because school is often on the way back home for us. I've also been trying to organize carpooling whenever I hang out with people, for example, all meeting at someone's house and then driving to the beach, which not only saves gas, and helps the environment, but also makes parking easier.
