I can tell you what lots of other important WRC people think. I talked to a bunch at rally spain.
General consensus was this:
Roads seem very good
They think the sport is "Coming back over here" and..
"It was coming up real nice a few years back, what happened?"
I would explain the SCCA etc... and then the dual sanctioning bodies, and they would say..
"WTF?! 2 championships w/ 30 entries per event?"
Lots of them also think our cars are pieces of crap, and our country is too big, and we dont have enough small rallies.
Some of the Brits I was talking to seem to think a championship is pointless without factories as well. (Including their own)
They told me they watch our rally on TV (USRC on Motorsport Mundial), and our roads look too fast.
Only a couple of them (M-Sport people) had actually BEEN to a U.S event. They told me the cars were crap

I lol'd.
