this isn't that much of a controversy, but i was talking about it with someone else and was curious what y'all thought about it. 
i personally think it's dumb seeing bikers on roads, there's a perfectly good sidewalk 2 feet over that doesn't have cars driving on it. i think it's safer for both the biker and the drivers. what do y'all think?
