Given the opportunity, I think everyone should have our balance.
Be careful though, not everyone works the same way.
Yeah, I forget sometimes that how things work with us, is completely disastrous for other couples, whether it's just fear for safety of the S.O. or just self sufficiency and focus. We know pretty well when to push and when not to push and leave each other alone so we do pretty ok.
Sounds like 23sLady and her dude are mutually supportive for trackdays though, and the dynamic seems right. Test and tune days are a little different from trackdays as it's racer practice and if you're inexperienced on the track, off pace, and nervous about close passing, it might be wise to wait. There's no passing rules like most trackday orgs, and it's a pretty broad range of experience out there. I still think you might enjoy doing the licensing clinic. I'm not sure what it's like in your region, but in the midwest the on-track stuff was really laid back with a huge range in ability. You can read about my experience

As for racing, I was about as scared before my first race as I was before my first trackday. In both cases, they were really nothing to be afraid of, and I still think both are serious fun. (But in different ways.)
