I would say it has a little impact...but not much. Obviously laser works off bouncing a beam off an object (reflection) and sends it back to the machine... when cops are trying to hit you with laser they are 9 times out of 10 going to aim for your plate or your headlights as these have the greatest reflection....now an old car with old paint with hardly any reflection and is dark would be the best option...but it would make very little impact on your car...some...but not alot. |
