... NASCAR doesn't try to "take the boat out of the equation". Tuning is an essential part of sailing or any other type of racing. ... Equally NASCAR doesn't have drivers change cars; the Olympics doesn't require a boat swap.
Aaah, but they DO! It's called the NASCAR IROC series (Internatinoal Race of Champions). They race in identically prepared cars. In their case, however, they can afford for each driver to have their own car. The Alter Cup Championships in the past couldn't afford 20 boats or an event with only 10 teams...so a compromise was created.
