Ok, so I have tried to keep my thoughts about this to myself on the forum, but I am sometimes amazed at the types of cars people are trying to put laser jammers on.
When you have a huge truck or huge SUV, you should not be speeding to the point where you would need them. Those vehicles are not meant to stop or maneuver quickly. One of the worst things to happen to road safety was the invention of the SUV.
People always start arguments about the dangers of speeding, and I am a firm believer that a good, alert, non-distracted driver with a competent car can be driven above the speed limit more safely than most other drivers on the road. I cannot say that I have the same belief about trucks and SUVs. They are not designed to go fast, and when I see people speeding in them, I always think "if you have to slam on your brakes or swerve to avoid something I pity the person you hit."
The point I am trying to make is that SUVs and trucks are inherently dangerous no matter who is behind the wheel. They can't stop or handle like a car, and if they hit something smaller than them it does serious damage, so you should not be driving fast in them, even if you are a good driver.
If you have a car, speed on!
