There shouldn't be a question of who is the better driver, since their individual sports are extremely different. They both drive race cars, yes, but that is about as far as you can take the comparison.
Danica has to compete with dozens of other drivers on the same track, manuvering through traffic and around the course, at varying speeds up to around 220 mph.
Ashley only has one competitor at a time, but she is in control of a car that has approximately 8,000 horsepower (more than the space shuttle), battling 5-6 G-Force at launch and 2-3 G's with the parachutes, at speeds over 300 mph.
Let's just say they are both incredible drivers and leave it at that!
