One of the claims now made is that even though there were problems with speed cameras in Baltimore, that other speed cameras which measure speed with LIDAR cannot be wrong. The implication that the device uses laayyyzeerrrs, which sound spacey and high tech, is supposed to lead one to believe the device cannot be wrong.
Of course, this is not true. It has been known for years that even devices which are properly calibrated, which theoretically include "error correcting" software, can still be wrong. One mechanism of error is the sweep effect, something which has been known to exist and documented for years.

here's a question i have. let's say there's a speed camera on a 3-lane highway (Rt. 50 business right in front of Wi Middle School). and let's say there is one vehicle in each lane traveling in the same direction. one car is traveling the speed limit (35 mph). one car is going 55 mph. and the last car is going 80 mph. they all reach the "snap shot" spot at the same time. how in the heck can they tell which car triggered the camera, and who gets the ticket? i've always wondered that.
They can't and most people just pay the fine. You are supposed to be able to legally face your accuser in court. Tell me where that went? Out the window for the sake of greed. Speed cameras are not right they morally are wrong and should be illegal.
