Anti-discrimination laws protect a person from being discriminated against because of their race, ethnicity, sexual orientation, or religion. There is unfortunately no specific law that protects a person from discrimination based on what type of car they're driving. When two cars are both speeding, and police are only able to stop one of them, they're allowed to pick whichever one they want, as long as their reasoning isn't based on illegal profiling of the driver. The fact that you have a faster car than the one not stopped is unfortunately not a defense, and neither is that the other car was going faster. Keeping up with the flow of traffic is never a defense to a speeding ticket.
What you can do is plead not guilty and request a trial where you force the state to prove that you were speeding, and that you were going 22 mph over the speed limit. It is also possible to go to court and ask them to reduce the fine, which they will usually do.
