Are you sure. The bags say 12!Well based on the bags we can absolutely see 11, but above the R in the RFF watermark, if the bags are placed equal distant apart then there should be another bag in the spot where we see people standing.
Checking a few other seasons of the race, I find no evidence of them ever breaking the bags into two sections. All seem space in a row (or arc) of equal distance.
But on the car front, production always has a least one spare on sight. And based off of two season (and others) all 12 cars (11 teams and a spare) are lined up.
I agree with mswood. It's too difficult to count the cars properly, and if the bags are the correct distances apart, that will be 12 teams. To me 12 teams fits with a two-hour premier better, because they could do the double-elim thing they had in TAR 10. If it's only 11 teams, then the first episode is definitely (and sadly) going to be the first two legs.
It's also possible that the 12th "team" could be crouched like Steve & Linda last season. Remember how short they looked?
I'll be wrong, though, just because puddin says 11.
