I dont ride a bike…but my thought is pretty simple…if you are on a bike you should be infinite more aware of your surroundings then if you are driving a car. A bike rider stands to recieve the most harm in any sort of an accident so in essence they should “respect” automobile traffic more.
Just like when you are driving your car and a semi trailer is driving near you…you are more aware of watching the semi because you know it will crush you and not even realize it.
