Yeah, doesn't make much sense IMHO to entertain Webber as #1 given the age discrepancy, I'd have all my money down on Vettel if for no other reason than to make sure you keep him in your stable. I like Vettel, he seems to have a about as even a keel approach as one can have, humble, and his talent is unquestionable.
I haven't taken the time to figure out the new point system for drivers, so really have no idea at this point who's in and who's out. It appears there are a few teams capable still of making tweeks to the cars which might change the dynamics of their cars capabilities enough to catapult any number of teams ahead, so I can't make a sound call on who wins it. Which is really nice compared to all the years when it was down to Ferrari and one other team after race one. Still, Red Bull IMO did the best at dealing with the change that eliminated fueling during the race so I'd have to go with Vettel as well.
I guess I don't really have a favorite driver from the current crop. Pulled for Hamilton his rookie year, mostly because he was a fresh face and the first of his persuasion to break into the sport. Was a Nikki Lauda fan, and then Alain Probst after, but that was more due to my appreciating McLaren in those days. I'd grown up watching and following oscar McLaren and had parlayed that over to the team he built later.
I was introduced to road racing back in the late 60's at Lake Afton just outside wichita where they held SCCA races one weekend a year, if you like racing I'd recommend checking in your area for any SCCA clubs and racing. Today the number of cars is way down, just too expensive a hobby for most but it's still has some good numbers in some classes and good racing.
