Police Do Not Have a Speeding Ticket Quota

A friend of mine is a cop and I’ve been lucky enough to go on a few ride-along trips with him. It’s pretty interesting to get a firsthand look at the job of a police officer. It gives you a lot of respect for the tough job they do.

When they’re not responding to calls, they’re doing paperwork and enforcing speed limits. On one particular ride-along, we spent a couple of hours trying to catch speeders. This was of great interest to me since I am a chronic speeder.

The first thing I wanted to know, what is the deal with quotas?

He said they don’t have a quota. Although, he added that if he didn’t write any tickets then it wouldn’t look like he was doing his job. Also, there are some cops who are trying to get promoted and write a lot of tickets, so if the other cops don’t write a fair amount of tickets then they come across as slackers. So, while there isn’t an official quota, these are the reasons why cops are driven to write tickets.

There are many tools that cops use to catch speeders. There are two speed measuring technologies, doppler radar and laser (aka Lidar, Ladar and “Laser Radar”). Doppler radar technology is the same technology that is used by meteorologists to analyze clouds and predict weather patterns. It’s also used at many stores to control automatic doors. Doppler radar units for law enforcement, come in many varieties: hand-held, vehicle mounted and automated photo-radar. (more…)

How to Prevent a GPS From Falling Off the Windshield

You’re driving along, minding your own business, when your GPS unit suddenly annuls its marriage to the windshield. It crashes into the dashboard, slides into the door, high-fives your passenger and bounces on the floor. Your GPS is not broken; but, it will be the next time it startles, then attacks your passenger again.

In the winter, it’s especially tempting for the suction cups on your GPS or radar detector to take your electronics skydiving. The suction cup relies on a vacuum tight seal to maintain its grip on the windshield. Cold weather, or direct flow of air conditioning, can degrade that seal enough that it can’t support the weight of the device.

The secret to getting a good seal: warm the windshield and suction cup(s) before getting them back together. You can warm the suction cup(s) with your hand or treat them like takeout food and warm them with your seat heaters. Using the defogger, blow hot air on the windshield for at least 10 minutes, then pull over in a safe place and apply the warm suction cup(s).

The idea is to create as much suction as possible inside the suction cups. Before you push it against the window, be sure the suction lever is all the way back, then push the suction mount HARD against the windshield, then push the suction lever forward. Because the windshield and suction cups are warm, you’ll get a better seal that should maintain enough suction to support your GPS unit or radar detector.

If you still don’t have any luck, try cleaning your windscreen and suction cups with glass cleaner wipes and repeat the steps above.
