just cus f1 cars and indy cars both have open wheels doesnt mean you can compare them..indy cars are cheap compared to a f1 car which is over a mil.. f1 is the leader in tech.. but as for comparing cars a nascar can get up to 80 to 100 mph in the straight aways on the lil oval tracks..but then on big tracks like dega it take then 5 miles to get up to 190mph...
