Radio frequency interference. Operators typically target the registration plate of the vehicle as this offers a flat reflective surface at an angle that will bounce the laser directly back to its origin and, with more than 100 measurements taken in half a second, the measurement process is almost instant. Some special devices exist that claim to detect when a LIDAR or radar is in use and warn the driver, but the speed in which a measurement can be made makes it virtually impossible to react and slow the vehicle in time.
