Because, 5 out of 10 times they are. I travel US 19 often, in my car and on my bike. I refuse to wear any gear that screams "I am a girl" so when I have my lid and jacket on you really can't tell. I can not tell you the number of times at a stop light someone will pull up beside me on another bike and the sec. the light turns green it is like "the race is on". I just giggle and let the fool speed on down the road.
