"filtering" ,"Lane splitting" I really don't get the need other than pissing off cagers that have been waiting to get going and frustrated already. For them looking in the rear mirror seeing and thinking "this asshole biker is trying to come by and wants to get in front F.ck them". Why aggravate another motorist with so much road rage going on. In Utah, sorry to say some motorist would pull out in front of you and even collide with you if traffic was held up with construction or heavy traffic. Even in normal traffic with cell phones and texting people make stupid lane changes without looking. I am for one not to practice this art. I have enough trouble staying alive on the bike. I also think that I saw a report of motorcycle deaths nationally being for the most part being at intersections and stopped or splitting lanes and under 30mph. Have fun for those that do. Stay safe! To many ass hat 18-23yr olds dying with stupid decisions. P.S. In Utah it is illegal, and if you have a passenger you could be charged not only with reckless driving, failure to yield, improper lane change. You also could be charged with reckless endangerment of a passenger. Insurance companies rule in Utah. Utah cops hate motorcyclist because of this type of behavior and the accidents and stupid deaths they see. Especially motorcycle cops.
