A car-free life can be a carefree life. Life without searching for parking spots, pumping the gas, waiting in traffic, getting speeding/parking tickets, and avoiding car repair/breakdowns can be less stressful and healthier. You don't have to be totally car-free to enjoy the benefits either. Being car-free for just one day can still make a difference. Imagine if everyone was car-free for just one day each week. That would be a 14% reduction in the pollution we create.
