>>1083982a scraped off scalp, cracked skull or actual brain damage make you look retarded.
being afraid of how you look just makes you seem like an overly self conscious amateur.
try bombing down a mountain and crashing due to some unforeseen occurrence and whacking your cranium on a large rock.
Try getting launched from your bike because a cager runs a red and slams into you at high speed with their booze guided murder machine causing you to hit vehicles, curbs or simply the road with your head.
hell, even if you hide on the sidewalk like a fag there are people who whip in/out of driveways a unsafe speeds without looking for kids/pets/cyclists(You).
honestly, wearing a full kit(that means a helmet too) makes you look like an actual cyclist instead of that kid who's afraid his schoolmates will mock him.
