Great post, Kevin.
It’s so important to get to know the guys in your run group. Go chat each other up. Build friendships. Share your on track experiences. Get to recognize each others cars on track. It’s too easy to be impatient or aggressive with people in other cars when you or they are anonymous. The moment you actually recognize each other it’s so much easier to have empathy and consideration for each other. You’re also less likely to behave like a knob when all you buddies know what car you re driving. 🙂
