For open wheel racing, Indycar is where it's at these days IMO. Since they changed to the DW-12 chassis, lost the stupid blocking rules and brought in some new talent and sponsors, the racing has been fantastic. Unfortunately, I don't care for oval racing, but it looks like its weighing even more towards road and street courses next year.

I wouldn't want F1 to become a spec series, but they need to do something to either make the racing closer or the technology development more interesting. The WEC has been the most interesting development series lately. It's guaranteed that Mercedes, Ferrari and Renault would never allow it, but opening up the engine regulations to allow more freedom could bring in other manufacturers itching to show off their hybrid technology as something sexy and powerful.
