This is best done from the right lane. The reason we need to be so alert while speeding is because we realise that most speed limits are set artificially low, in order to raise local revenue. However, you should obey the proper safety rules of the road, as well as maintain highway etiquette. Vindictiveness and ego-inflation do not belong on the road. Also, signaling lane changes is VERY important, since it will let others know what you're doing.
Uncertainty necessarily keeps speeds down.
I'm convinced if everybody followed simple right of way laws all the time, we could easily be averaging 10mph more on the highway. A red Porsche will obviously get more attention than a gray Nova. I used to make high speed runs between Buffalo and NYC back in college, driving a battleship grey '77 Chevy Nova. It was totally nondescript, a wonderful V8 speed machine. If you can, try to get a dark car.
