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.
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!
At this point, I think I'm supposed to whine about how "modern rallying doesn't hold a shadow to Group B" :)
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.
