I dont think Type R's intial post was arrogant. Just a friendly wager. Now if he said.
Hey Sky lets race so I can blow your slow Mustang away. Domestic Turds......
Then that would be a problem. Type R said nothing about expecting to win the race, especially when Sky squeezed the Charmin (Bottle).
He said nothing offensive, well that I saw. Maybe I just read into his post what he meant.
