I enjoy Nascar because of the constantly changing strategy. Watching some of the long tracks can be like watching paint dry but in the end there is almost alway an exciting finish. I use to enjoy IRL and F1 but there is so little passing that it bores me to tears regardless of how exciting the track is.
The new car simply adds more strategy to the racing hence why I like it more than the old car. The old car was getting to the point that whoever had the most money could tune it better than everyone else and win. Kind of like Ferrari and F1...
I wish we they would put more road courses in Nascar and at the same time improve the car to bridge a little bit of the technology gap.
