Other race series manage (on the tracks used more than once a year) to overtake quite a lot.

Some of them certainly don't help, but its clearly an aero issue, there are some tracks that have remained the same for many many years. Rule changes could help. Saying that some of the newer circuits are obviously poor for overtaking but you cant put all blame there when other series manage fine.
