FWIW Indy is not the best oval to test skill. It's like Daytona. All you do is hold it to the floor and stay on line. Kurt Busch (NASCAR driver) ran the Indy 500 in 2014 and finished 6th, and he had literally never stepped foot inside an open wheel car before. If you want a true test put them in an IndyCar at Iowa or a stock car at Darlington. As far as F1 drivers on ovals, the best example of this would be JPM when he came to NASCAR in 2006. He had a couple decent seasons, but in 255 races he only won twice, and both were on road courses. The equipment he was in from 2008-2010ish was very capable of winning races too. And this isn't a knock on Montoya either. He is one of my favorite drivers, but he just never could replicate the success he had in F1 and IndyCar on the Cup level. Marcos Ambrose, a two time V8 Supercar champion, and one of if not the best in that series at the time, also came to NASCAR in 2007. In 227 races, he also won twice, both times on road courses. How about 4 time IndyCar Champ Dario Franchitti? He actually had some experience in IndyCar on ovals, so you would think he would have had an easier time making the transition. However, in 10 Cup level starts in 2008, he had an average finish of 34.3. In the Xfinity series (easier lower level of NASCAR filled with less experienced drivers), he started 18 races and had a average finish of 20.6. He never won in either series. So there you have 3 examples of very experienced and proven champions from other series that tried to make the transition and went 0 for 492 at the Cup level on ovals. SofiaSpeed, why don't you ask them how easy ovals are? There are a few reasons for this I think. One is I think most of them know that transitioning from open wheel to stock cars is easier than visa versa. A stock car driver that has been racing on ovals since they were five years old just isn't going to move over to F1 at the age of 35 and compete for podiums. That will never happen. Two, the big stars like Johnson, Ky Busch, Gordon, Stewart, etc already make a ton of money over here in the states, plus all there families/friends are over here, so really no reason for them to make that move. And third, I really just don't think they have any interest in trying open wheel. Heck, none of them have even tried to compete in a IndyCar season. And logistically and competitively that would be a easier move than F1 would be.
