Utah has a decent shot at passing it this year. Passed the House now in the Senate and Highway Patrol came out in favor of it. Its not California style, would only be allowed on streets with less than 55mph speed limit to filter to the front at red lights. But its a start.
I heard something about the Oregon bill having a good chance as well. But couldn't find any reputable reports other than the typical 30 sec new story about them considering it.
Texas thought THEIR's was going to pass. Even went so far to put it in the books with an effective date....never made it. That being said, I still "filter" when it can be done safely, and my boys and I ride side by side; we have comms and plenty of practice for it to be done safely.
