I don't own a car. In the city, I walk everywhere, take the bus sometimes. My bike has two flat tires, should probably get them fixed. Bigger cities: trams or metros.
If I'm travelling long distances, I take the train. The train takes me basically anywhere in Sweden, Denmark and Germany without much hassle. Prague too. Further than that (England, France, Spain, Italy, etc) I take the aaaeerrrooplane.
