What about the
cosine effect, if you get caught speeding by an officer with a radar handheld gun? It is simple to explain and almost nobody thinks about it.
You can check also
here for an explanation of how an effect that diminishes speed readings can be a
defense. I've used a radar gun many times and I can testify it happens, in case you need it and
if you're actually innocent. Not all judges and officers are familiar with it. I've actually seen the confussion in the faces of the officers when they failed to realize that at less than 120 meters, located at the side of a wide road, their radar guns were useless. The second time I served as a witness, the police officer arranged for me to give an explanation of the effect at the police station to all officers. Not bad for a simple trigonometry relation!
