It is an improperly delivered summons though so you might be able to just ignore it until they come get you. I doubt that they can legally deny you an appeal for failing to respond to something delivered by regular mail. Now if it was delivered registered mail, you should just pay it.
BTW, the photograph clearly show the car entering the intersection (busy , no less) with a car waiting on you in the left turn lane and now car behind you. I think you should just pay it.
Looks to me like Darth needs to have some discovery from the city and company operating these (s)cams.
