For me, endurance racing (WEC) is quite a bit more fascinating and impressive than F1. Racing a car on the cutting edge of race technology for 2 hours is one thing, but 24 hours is a whole different ballgame.
The other thing that WEC has that Formula 1 doesn't is the chaos and excitement caused by multiple classes of car competing at the same time. It's not just a matter of negotiating your car around all the other cars that are pretty much identical to yours. You have to negotiate around cars that are both slower and faster. Dealing with traffic is a major aspect of WEC, and it's something that's entirely lacking from F1.
If you like the chaos and excitement of WEC you should come on over to WRC. $5/month for 3-hours of live streaming HD content per Rally, including full on-board cams for every major driver and stage:
I mean c'mon, Kris Meeke with an accidental exit into a car park with just a few corners to go while leading Rally Mexico. You can't get much more exciting than that!
Absolutely. I mean, could you imagine F1 drivers having to negotiate the track with the 911s, Astons & Corvettes? They'd throw a damn hissy fit.
Not only does it make the race exciting from logistics/entertainment perspective, but at any given time there are multiple first place battles occurring. It's hugely entertaining.
