I'd like to stress one of my motivations to become car-free
My city, Lisbon, has became many years ago an open-air-auto-salon.
Look this video and you'll understand such consequences and my motivation to become car free and bicycle fan
And then obviously the environment, my own health, money, and freedom.
Yes, I feel myself depressed when I don't feel cool air on my face during the chilly mornings :)
