I have a crowded left turn to get through on my way home and this has become a huge issue there, most cars take 2-5 seconds to get moving when they're at the head of the line. I guess they figure there's no way there's going to miss the light in that position and it's a great time to play Candy Crush. This can easily keep a half dozen cars from making a light they should have had easily, plus people get steamed and run the red because they figure that has become their right as a wronged driver.
Big Lexus SUV did this at that light when I was right behind it, then they did the same thing going straight at the next light a mile or so down the road. The second wait was so long that I gave them a very quick toot of the horn...I watched the lady look up from her phone, give me the evil eye in her mirror, shake her head, and then SLOWLY get going while she put her phone away. She was still crawling when we got to a passing zone after another half a mile, with no oncoming traffic I lit it up and passed her with some authority. She immediately sped up to try to block me (no chance), gave me the bird, and flashed her lights like mad when I got back in the lane.
Yeah, I was the big jerk there, right?? Funny thing is I think I knew who she was, a pompous witch who took joy in making the kids miserable when she "helped" run a group my daughter had joined years ago. Told my kid about her driving and she said that lady's daughter can't even stand to be around her.
