If I'm honest, I don't really care where they race so long as the racing is good and close, and it's the spectacle it should be. It's nice that we get a round in the UK but it's too bloody expensive, the weather is usually crap, and I'm not really a fan of Silverstone anyway.
Spain and Portugal having 5 rounds between them, almost 1/3 of the season, is just crazy though. So from this point of view I'm happy they are expanding in to new countries and using new circuits and nabbing some of the Iberian races.
Dorna's money saving credentials aren't good. Why fly from Europe to Laguna, then back to Brno, then back to Indy, then back to Europe. Madness, except that if both US races were back to back how many tickets would be sold in total? Would people go to both if they were only 3 weeks apart? No, so split them up and sell more tickets, but that means flying there twice.
If it were me, I'd keep Qatar as I like the spectale of them racing under floodlights and bugger the environmental costs (we've all got energy saving bulbs at home which surely evens up 5 or 6 nights in the gulf with the spot lights on?). Sack Indy from the calendar, sure the place has history but the track is dull dull dull (from my sofa anyway). Oh, and bring back Hockenheim and get a race in at Monza.....
