Not much to say, really. It was clear from the beginning of the season that Michael Schumacher was going to win the drivers' championship, and he did. Ferrar was going to win the Constructors' championship, and they did.
The season was astonishingly dominated by Ferrari and its drivers. They, and Bridgestone, have clearly figured out how to win under the current regulations, and no one else could stop them. Since it isn't really clear what will change for next year, I am expecting (although not looking forward to) another season of Ferrari domination next year.
In other news, Villeneuve will drive for Sauber (Ferrari Jr., so to speak) next year. Many see this as a foot in the door to get him into his father's old seat at Ferrari. While this might be an interesting combination, the record of Sauber drivers moving up to Ferrari is pretty much nonexistant. So I'd encourage a massive exhalation in Quebec.
As for CART . Hmmm... Is CART still racing? Somehow they lost my interest this year. This was probably a result of sticking their telecasts on SpikeTV (TV for guys?) and not carrying races live. The result was too ghastly to watch, so I stopped. I understand that Bourdais was the champion. As I have seen observed elsewhere, however, it really isn't clear that having a French champion is going to do a lot for their popularity in the US.
And NASCAR? Well, the new bizarre points system has produced a close race for the championship at the end of the season. Still, you have to strongly believe that a full-course yellow is a necessary part of racing before you can buy into it being a key part of the championship. As long as NASCAR continues to add vanilla 1.5 mile ovals to its season, I will continue to only watch those races that are interesting -- long tracks (Daytona, Talladega), Short tracks (Bristol, Martinsville), Road courses (Sears Point, Watkins Glen), oddball courses (Darlington, Dover) and the original 1.5 mile tri-oval, Charlotte. For the rest, I'll just check the results online and let the race fade off TiVo.
