Abbey,

What I'm hearing is your attention to detail, ability to learn and unwavering concern for safety. Yes, it is absolutely a plus - these are skills, regardless where you learned them. It sounds like there is an uncanny parallel between professional racing and flying. Highlight the parallels of what is involved with being a successful driver rather than the industry itself.
Rickair is right on the money - it depends on how you present your past experiences..and how you present yourself.

These were very real parts of your life and if they showcase your positive attributes then they should go on a resume. However when describing your job duties keep it to a minimum, using buzzwords that mean something in aviation if possible. I simply don't understand how it could be a red flag and consider you a risk...??
