I don't even drive that much, but I've seen this behavior twice in the past week and a few more times in the past few month: Driver stopped at non-sensor intersection in straight lane. Left turn arrow turns green, straight solid red stays red. Driver starts going and proceeds straight through intersection. I'm left wondering if this is part of the general breakdown of norms following Covid, or aging boomers not caring about tickets, or what. It could just have been a spurious pattern too, of course.
