Mods or no mods, I'm just in it for fun.
Measuring my times is a useful for the insight into the progression of my skills. Comparing them to others' is useful as a way to have some idea how much more I might improve. That's really the only reason I care about others' times, though.
I'll never be one of the best amateur drivers, and the pros are on a completely different level. So I just try to have fun and seek new experiences.
