What should I do with my speeding ticket?

Go to the Department of Motor Vehicles in your state or to the Clerk of the Court to receive a LIFETIME driving record but do not tell them why you need it. In Florida one has to get this record from the Clerk of the Court.
I do not know how it is done in your state but looking at this record will tell you what is on the record. If you simply go to the arraignment for the ticket the Judge or Hearing Officer may agree to withhold the points...which means your insurance company cannot raise your rates if their is no points...at least in Florida...but it must be true in Washington because the insurance companies are national.
It is always smart to try to get a deferral if possible. Although a police officer will not tell you this - speed accuracy is iffy with a "pack" of cars such as you have described due to the angles of the radar itself...and attorneys know this.
Good luck...it is not the end of the world.

This sort of thing happens a lot in Whatcom County where the police are trying to catch speeders along I-5. Hiring a lawyer is a good idea for many reasons. For one, if you hire a lawyer, you will not need to attend any court proceedings as your counsel will go for you to all hearings. Secondly, the Infraction Rules for Courts of Limited Jurisdiction provide numerous ways for your ticket to be defeated. Some of these involve requesting discovery, which in Whatcom County, never comes, or challenging the speed measuring device. Usually, hiring a lawyer costs just a little bit more than the ticket. But winning and keeping the ticket off your driver's abstract where the insurance company can see it a raise your rates, is worth even more. You can certainly mitigate and get your fine lowered or even get it deferred. These can be good options as well. You get one deferred moving violation and one non-moving violation every seven years and it costs about $150 payable to the court clerk in court costs to get the deferred.
