Just today on the way to work, the highway opened up to the right so I passed several cars at a decent speed, one of which was a G35.
Up the road a bit, I saw the G35 charging hard in the left lane ... as he passed me at about 95mph or so, I pegged the gas and got right behind him ... "it's blower time!"
I was able to get right at his speed from 80, and then broke off into the right lane. I was moving past him very surely, so I looked over and smiled and kept the speed up until we hit traffic ahead. It is hard to say sometimes when other drivers are really trying, but seeing as I went back to my GPS to see that my speed had reached 137mph, I'd say he was trying.
On another note, about 2 weeks ago, I was heading up the highway and saw a Mercedes coming up a bit quick behind me. While going the same speed, I stepped on it, figuring I'd teach him a lesson. At about 130mph, he easily cruised past me ... I did not catch the car's class, but did catch the 4 exhaust tips and the "55 AMG" badge. My 3.2 liter V6 supercharged falling to a 5.5 liter V-8 supercharged is not such a bad thing .... but now I want THAT as my next ride!
