In California VC Section 28150, a LIDAR jammer in of itself can result in a ticket. Best to coast and switch it off very quickly. In my experience only about 20% of patrol cars used LIDAR, the majority seem to be using K or Ka band RADAR. X band is so prone to false alarms and never had an actual alert on it that wasn't a speed sign so, disabling it is common.
Actually, more than a ticket. They can impound your car.
However, most systems have an "alert then disable after X seconds" system - giving you time to slow, then disable the jam, allowing the LEO to get a 'speed' eventually (and chalk it up to his crappy LIDAR gun)
Take a look at the grilles of some exotic / fast cars. If you see devices inset that look like IR blasters -- those are LIDAR jammers.
