Nowadays it feels like an utopia to have car free cities to me. People are used to have and utilize cars not to mention the power of the oil companies which will not let their business sink.
But of course we can have a sustainability in our conscious and improve the effectiveness of cars. The not so new tendency of cars run by electricity is a good start. Setting a fee to the use of cars in the city center is another good alternative.Using other means of transportation is healthier and more environmental friendly. There are a lot of cities who promote the use of bikes and have as many bike paths as streets. Also taking public transportation is a way of saving energy and pollute less.
I think it is possible to have cities with less cars every passing day. The people should be shown that there are other alternatives that are as comfortable and cheap as driving your own car. And if the new option is even better for the ecosystem we live in and our life, then that is a plus!
Hopefully we will be more and more aware of the problems caused by cars for the sake of the environment and our own. And who knows maybe Hamburg indeed becomes the first car free city...
