There aren't many speed cameras here pulse, matter of fact I don't know of any still in use in Texas.

Back in the early 70s there was one called an Orbis that sat on a pole in a wide median between 2 sides of a 4 lane wide stretch of road in a suburb called Grand Prairie. It took its shitty little pics and mailed out tickets ... in between bouts of bein blasted to hell with shot guns or havin gallons of paint dumped over its lense. Eventually they got tired of rebuildin or replacin the damned thing and gave up on the idea since they were spendin more than they were makin off of it. Texas baby, gotta love it!!

But ... if you get popped street racin by the wrong cop and wind up in front of the wrong judge it can be quite an expensive deal
