Driving on deserted stretches of hiway, near a couple of air bases here in Arizona, my lazer detctor has exploded with activity. No cops around (Arizona didn't have lazer at the time anyway). No construction, ie. lazer levels about.
Only thing around were air force jets, f-16s in one occurance and apache helicopters once. These were not isolated instances has occured to me at least 3 or 4 seperate times.

Has anyone else experienced or heard of military aircraft using civillian vehicles for mock target practice/ lazer sighting?

 

no, but if they are lasing something that has angles, and most stuff does, it can deflect part of the beam and bounce all over the place
