O, that's a matter of choosing lesser of two Evils.. NASCAR is all about drama and commercialization now. Everywhere you turn BAM! there it is. All day long on TV. Indycar on the other hand is killing open wheel racing in North America. Champ Car series is much much better.
I think I'll pick the Indycar series simply on the fact you don't hear/see nearly as much about it, so you can ignore it easier. :P
[EDIT] Seems I was slow. LHD is preferred by myself. I feel wierd on the right hand side of a car...[/EDIT]
LMP or GTP?
