What else would cause a laser signal?

Twice my Pro 78 has gone off with a laser alert on the highway.

Here in Illinois, the State Police stand on the side of the tollway dressed as construction workers and use LIDAR. They then radio ahead and a patrol car pulls over the vehicle clocked speeding on LIDAR.

After I got hit with laser, I braked and really looked around. I could not find a patrol car anywhere. I checked the ramps and everywhere.

I was going through a construction area with workers all around.

But I am wondering if anything else can set off the laser warning on the Pro 78 besides genuine LIDAR?

Most common alerts in my area would be the laser adaptive cruise control systems found on many Toyotas and Lexus vehicles-

In a construction zone they could be using lidar-based surveying equipment. Basically they're the same as police lidar guns but measure distance only, not speed.

Most/all of the companies that make police lidar guns also make lidars for surveying. Laser Atlanta has the Advantage unit for example.

A few times when I used to drive with my RX-65, it would scream laser while driving near airports and military bases.

Airports for sure. Confirmed around CLE, maybe because you can get REALLY close to the strip.

Let's see, the V1 picks up red neon, Chevy Trailblazers, and even a setting sun as LIDAR. Could have even been a TV remote...
