There are many different paths to becoming a race car driver. It depends how much money that you have. If you happen to be very wealthy, there are not many barriers to entry. You buy a car, hire a racing team, and qualify for races. So if you're already rich, you need to practice driving a lot.
If you're not rich, you need to begin by racing locally. Then work your way up to more and more expensive cars in more and more competitive races.
Based on my research, I would want to be a racecar driver!
