i am not saying they cant learn that and be successful, but it would take a while. and probably longer than most team owners would give them.

another example: DTM is very popular in Germany http://www.dtm.com/index.php?lang=en&

there's a couple of ex F1 drivers who were later driving there - including Alain Prost, Mika Hakkinen and David Coulthard. None of them ever won shit there. Because it's a completely different way of racing.

last years DTM champion Paul di Resta is now driving F1 - we'll see how good he's doing the other way round.
