I got 2 laser falses this evening on an overcast day, with no infinitys or trail blasers around.
It happened on a freeway the first time, and the only cars that were in front of me were an older Honda, and a Dodge truck. Then I got another not 5 min later with no one around. Neither time did the ZR3 go off, and I never saw a LEO or anything. It has happened before but never twice in one trip, and if it did it didnt happen very close together.
What else can cause a laser false?
