Hi, we haven't really met. I'm rather sarcastic.
My city is known for it's aggressive drivers. I want to say we rank in the top 10 in the country and first for speeding or something? Anyone in the fast lane is usually going about 80. The center lane is likely going 80...and likely the whole line of 18 wheelers are all going 80. It's just what we do. I've hit my governor simply by going with the flow and being in a long line of cars going the same speed. So for real, stay out of the passing lane.
But really, it's a very good way to get killed by trying to merge onto the 70mph freeway going 40 and people from other states do it ALL THE TIME. I think it's because our freeway system is truly nuts and does not work at all like it does in almost the entire rest of the country.
The last bit was tongue in cheek, because Texas.
ETA - Really thinking about it, 10 over is standard around here across the board on every fairly major road, except in the cities that only exist to be speed traps.
