My choices would be:
- Bahrain - I don't like the track and the races it produces, but it would have been interesting to see if the new regs this year improved it at all. On top of that, it appears to be a very sterile venue, lacking any kind of atmosphere. Maybe someone that has been could confirm?
Monaco - It's full of history and it's cool watching cars racing around the streets, but there's very little overtaking, and if F1 really is committed to improving racing and overtaking opportunities, this needs to be stripped from the calendar. Chances of this happening are zero.
Turkey - The attendance figures are shocking, and quite simply, if very few people care to go see it, put the slot to some use. Either to break into a new market or to a country where there is a known following of F1
European - What the heck, how we can end up with a country getting 2 races a season is beyond me!
