Hey now, I don't think cops are bastards! My uncle is an Inspector up in Staten Island.
But to answer your questions, I just checked my manual and you're right - I should reinstall the blinders on the side of my car to the front/rear. A laser gun is not accurate when shot from too extreme an angle. And yes, they would fool any laser gun pointed in my direction, regardless of where the beam is aimed.
I have serious disagreements with your speed limit enforcement tactics. For instance, I was traveling in a 65 MPH zone one day, going around 70 - 75 with the flow of traffic. Coming around the bend, EVERYONE slammed on their brakes. I was nearly rear-ended by the pickup behind me. Everyone slowed down to 50 MPH... I thought there was an accident....nope! Just a cop sitting around a bend in a blind spot. God knows how many near-misses he caused that day.
When you speak of higher density areas, highway speeds tend to limit themselves. If there's heavy traffic - there's nowhere to go anyhow! I'm talking about open highways. There's a reason the Autobahn is safest roadway in the world, even when it's congested with rush hour traffic.
When the speed limits were removed from Montana's highways, the average speed only increased 2 MPH. Yes, you had the jerks who drove recklessly and tailgated, but WE HAVE THAT NOW. Every study points to three major factors in driving habits that are VASTLY improved when speed limits are removed on major highways:
1. Lane courtsey improves.
2. Safe-distance driving increases, tailgating drops dramatically.
3. Seatbelt usage increases.
Removing speed limits also allows traffic enforcement to concentrate on the REAL cause of fatal accidents - reckless driving and tailgating. During the Montana Experiment, tailgating, like in Germany, was considered a HUGE offense. It came with very heavy fines.

I would really like to make it clear that I do not dislike cops. I have a great respect and admiration for the job you guys perform. Sure, there are some bad apples, but there are bad people in EVERY walk of life. All my hostilities towards speed limit enforcement are directed towards the individuals in the government who enforce them purely for profit, even when confronted with a study that shows thousands of lives were saved by removing them. You guys are just the messenger, nothing more, and as we all know, you don't shoot the messenger.
