In an interview with Autosport, the main F1 track designer Hermann TIlke has said that he thinks street circuits are the future of F1. He says that organisers really need to start bringing F1 to the people, and the people are in the towns.

And for obvious reasons you can hardly build permanent racetracks in the middle of a town, so you then come logically to street circuits.

- Hermann Tilke

Isn't he just talking himself out of a job??
