As we all know, a metallic silver Chevy HHR was used by GOL for their latest 2008 laser jammer tests. This vehicle was a frigging nightmare for the laser jammers to protect since the HHR features numerous areas where a laser gun's signal could be readily reflected from. A lot of these reflections would be rather intense.
Following is a photo of a similar HHR, but this HHR is missing the low mounted front fog lights.
-- The two light green rectangles indicate where the front jammer heads were mounted during the GOL tests.
-- The front bumber (encompassed in orange) features a vertical front surface.
-- The side mirrors (encompassed in orange) feature chromed forward surfaces.
-- The front grille features fully rolled over horizontal slats. The shapes of these rolled over slat edges is indicated by the orange curves at the left edges of each of the front grille's horizontal slats.
-- Finally, all direct and mirrored reflections which would occur for lidar gun angles between zero to 5 degres off-axis towards the driver's side are indicated in red. Note that most states design their license plates to reflect lidar. Thus the entire front license plate area is marked with a large rectangular box. Even without a front license plate, there are an awful lot of areas marked in red, aside from the vehicle' highly reflective metallic silver paint, which would efficiently reflect lidar gun signals back towards the lidar gun.
So, after looking at the photos, what do you guys think? Was the Chevy HHR indeed a "worst case scenario" test vehicle for the jammer systems?
Here is a photo of the inherent curvatures of both the front grille and front bumper:
