The cop gave me an expensive ticket and let me drive away.
What caused you to speed in the first place?
I like to challenge myself like that sometimes.
No wonder you got a ticket, you ask it for yourself by crossing the speed limit. Speeding laws are in place to protect people including you so you should obey them.
I'm going to challenge the police officer by appealing this ticket, if he wins, I win.
Driving too fast is going to put you and other people into danger. You are also breaking the law when you go way over the speed limit. Challenging the police officer for the ticket is a little rude to be honest since you even admit to speeding.
