That's a pretty sorry equal protection argument. There are plenty of things we have both criminal and civil penalties for. Also, the "safer to run it in the conditions" argument is pretty weak, given that means the speed was unsafe.
That said, it raises a very fair point that it eliminates any discretion and contextual assessment. I have related elsewhere (under a sock) my story about speeding cameras in DC. Suffice to say the protest mechanism does not take into account circumstances that would ordinarily call for a police escort rather than a speeding ticket. (Nor, I'm told does it ever take into account any excuses--it's a rubber-stamp rejection of your appeal. But that's the due process issue, not the ticket in the first place).
