This is at ~400mm equivalent zoom.
Rightmost part of plate is covered with matt tape (~=lasershield).
The circles around the turn indicators are 100% flat. The one on the left side of the picture is bright, showing I am exactly perpendicular to it. I took many pictures, and this one had the most reflection from the headlights (worst case scenario).
Notice the grill has a chrome surround, but is not reflective since it is slightly angled.
Conclusion: Take a picture at night and at max zoom (perpendicular of course), to SEE what a lidar would see. In this case, even with protection, the front plate is brighter than the headlights (even in worst case conditions).
I wonder how the picture would have turned out if the car was silver / white.
For photography lovers, set the shutter speed to the maximum flash sync supported by your camera to reduce light from sources other than your flash. 1/500 sec in this case.
