It is obvious both are at fault here as is true in life. I ride a bike to work regularly and drive  often as well. I have seen both auto and bikers break the law often. I almost always ride the bike on sidewalks as I travel along Tudor most of my cummute. What is really scary is many auto drivers NEVER look right when turning right at an innersection because they are only thinking of motorized vehicles, not bicycles or pedestrians. If I was not watching the drivers head/eyes I have been almost struct multiple times when I have the Right of way. I have flashing lights on the front and back. You can't miss seeing me if you PAY ATTENTION. This is not even considering those looking down at their phone which I see very often. I have been guilty of not looking as a driver as well but much better since I bike. Might do some drivers good to put on the shoes of a biker and help their health as well. Do bikers break the law? Absolutely and they need to stop.
