Interesting enough, it tends to happen most with "modest" cars like G35s, A4s, etc. Though one guy in a mercedes AMG whatever did rev up at a light next to me once.. at 7 in the freakin morning
.. should have taken him though. Looked up the car's sprint times and realized I probably could have had a shot. Silly Mercedes drivers!
What annoys me more is the people who ride your A$$ when they see that you're, uh, driving swiftly.
