Our world without cars

Not having a car I woke up this mornings and left our flat entering a totally empty street. I like the moments when my brain is tricked. For a split second I felt like there had been some kind of apocalypse and all cars disappeared. I liked that idea :-) after a second I realized that there was a street cleaning day today and all the drivers were asked to repark their cars. But anyway, imagine you wake up to the world of no cars...
