11. Radar Detector
Radar detectors are a burning question in the car community. Some states consider radar detectors illegal while others allow you to have them. But, if the police prove that you have been using one, you’re going to get a ticket. Also, they are becoming obsolete due to a new generation of police speed radars that use cameras and calculators to determine your speed. That means there are no radar waves to detect or jam. In most cases, police radars send radar waves that bounce off the speeding vehicle and return to the radar, which calculates the returning speed; thus, showing the speed of the moving car. Radar detectors work as a jammer or as an alerting device. The jammers cause police radar to get bad return signals and disable them from reading the speed properly.
The alerting device tells you there is a radar up the road, so you can slow down in time. In the past, radar detectors proved to be effective, saving many drivers a lot of money. The problem is they also gave motorists the confidence to drive faster, which is unsafe. Today’s radars work more like a camera that calculates the moving speed with great precision. And since there are no radar waves, it is impossible to jam or detect them. So if you already have a radar detector, conceal it and never put it in a visible place like the bottom of your windshield. And finally, if you are planning to buy one, save your money and just drive the local speed limit.
