Yes, there are defensive driving courses offered at most racing schools and they're generally a prerequisite for taking more advanced racing courses but are also pitched as a terminal course for people who simply want to improve their daily driving skills. They'll take you through some of the basic theory of safer driving and then take you out onto the track to practice some basic defensive maneuvers. People who take the course generally say that it has real, long term effects on their driving as it provides them a mental framework for how to evaluate traffic from a fundamentally defensive perspective and they find themselves practicing the same skills decades after they've taken the courses. I'm not aware of any long term, longitudinal studies on whether defensive driving courses decrease raw accident rates but any study would be tricky to do since people who self select for defensive driving courses are likely to have any number of confounds that would make observational studies less than clear.
