    "The rear or front of a motor vehicle is very inefficient at reflecting a microwave police radar emission"
    This is true. Any small piece of metal close to the wave length of the radar is more efficient. AT a small % above half wavelength it becomes super-efficient.
    I think the new radars have a wavelength about 1cm.
