I notice most of our group don't have them...
When someone in your group makes fun of you, your dopamine level drops. That makes you slower.
Plus, the visor adds 12 grams of "rotating weight," cuz your head rotates when you look around. And too much rotational weight makes you slower at 20+ mph.
All of this is backed by wind tunnel testing results.
