We use to think F1 has a lot of problems but thats not true at all. F1 has got great drivers, great cars and races (although these both can improve) and overall a great great audience and market value.
Jean biggest problems in my view are to make WRC something worthwhile and to have a decent World Sportcar Championship. FIA GT1 is a good start, but I still dream about a WSC that includes LeMans, Sebring, Daytona, Spa, Nurburgring, Monza... and why not Buenos Aires and the old A1?
