This would be good for people to record on a per race basis without having to manually record. Race sessions vary in time so this would be amazing due to the possibility of people forgetting to hit stop on the record or even forgetting to hit record from the start. You could also have Qualifying and Race recordings seperate.

As Sim racing has become more and more popular with more and more content available on streaming and video platforms (eg twitch and youtube) this would be an amazing feature.
