Technofreak: Your description of events makes them sound quite extreme/dangerous, not something that's seen very often if at all in my experience.
From what you wrote in you first post you seem to attract more than your fair share of these events. I had to wonder why.
Its probably because I'm a really really bad driver. I follow road rules to the letter. There aren't many around who do. I'm one of those muppets who on the open road, if I see road works and the signs say 30kmh, I do 30kmh. All the way until the increase in speed sign. Thats 30 gps speed incidentally. Yet people honk their horns, flip me the bird, pass me on the inside, or plain just try to intimidate me by getting dangerously close.
But I can deal with that, when possible, I pull over before roadworks to let all the speeders go past. But there is nothing I can do about traffic lights, apart from I guess to plan my route to avoid them.
