Is this a really dangerous AND dumb law, or am I misguided?

The other day, I’m sitting in traffic at a red light. I’m about 12 cars back on a 6 lane (3 in each direction) artery in SLC. That’s when I hear what sounds like a gunshot right outside my drivers side window, and see a motorcycle ripping between the rows of cars waiting at the red light. Something on the rider or his motorcycle hit my side mirror and tore it off my truck. Just as he got to the front of the line of cars (by riding between them), the light turns green and he’s gone.

So I hop out quickly (in traffic) and grab one of the trim pieces to my mirror (most of it was still dangling by the wiring harness) and get back in my truck. I rolled the window down and brought the rest of the still-attached mirror into the cab, so as to keep it from scratching the **** out of the door. I called the sheriff’s department to report the accident (not that I had much info to give, as it happened so fast and motorcycle plates are so small). As I’m relaying the incident to the dispatcher, she asked me something that literally stunned me - “were you crowding the white line?” Excuse me?? “Well if you were, this incident may have been at least partially your fault.” WHAT? Apparently there was a new law passed last spring called “filtering”, and you guessed it, this new gem of a law allows motorcycles to “filter” between rows of stopped cars at traffic lights, and roll right up to the light.

Is it just me, or does this law seem completely asinine? Luckily, most of the damage to my truck was easily fixed, but it could have been much worse.
