Complaining about "going 90mph on a 65mph speed limit" is not a "speed trap"; a speed trap is a situation set up in such a way that many well-intentioned people make an honest mistake. Things like confusing signage, sudden and/or unusual change in the speed limit, and so forth.

This is just someone sour because they got caught speeding. For reference 90 mph is 145 km/h, it's pretty fast, and the limit in CA seems to be 70 mph at the most. Driving at 90mph is always wrong unless you are rushing someone to the hospital or similar emergencies.
