Speeding Ticket - But date to appear in court is incorrect (can I get out of this?)

I just got a speeding ticket today while borrowing a friend's car. I had been driving for about two minutes when I got onto the Interstate. I hadn't been going but a mile or so when I got pulled over for doing a 75 in a 55 (The officer paced me). I'm thinking of arguing that, since I was unfamiliar with my friend's car, I wasn't used to its handling and in trying to accelerate and merge on the interstate I wasn't watching my speed. Also, on the ticket the court date is written as "Fri the 21 day of Dec 2003." The 21st day of December is a Sunday. I'm assuming that the correct date is the 12th, but I'm not sure how to play dumb and show up on the 21st without having had a warrant out for my arrest. Any ideas?

Also, does the Manual button change up the torque applied to the front/rear, or just lock out first gear?

Thanks,
