In Louisiana, there are several boxes that the cop can check on the ticket to show how he got your speed rating:
* pacing (following behind you at a constant distance and checking his speedo)
* Radar (duh)
* Timing (He got radioed in by the plane that times you between two white marks on the road)
He does NOT need radar to give you a ticket.
However, he probably WILL need radar to make the ticket stick. If you get a ticket and that bastard says he paced you, smile, thank him for doing his job, tell him you're sorry and that you'll slow down, and immediately call your lawyer. You can beat this ticket. How does that cop know his speedo was calibrated correctly?!! Is he positive he was following at a constant distance when he checked his speedo? etc
Timing, this could be easy to beat, too. A plane bumping around all the time is hard to see a tiny car on the highway from. Also, the cop in the plane might not have done the correct calculations to figure out the speed.
If all else fails, go to court, and the cop probably wont' show. If he doesn't show, you're off the hook. I've heard of millions of people beating a ticket by doing nothing more than showing up in court.
Hope this helps!
BTW, you can beat a radar ticket, too. Oh, and you have a good chance at beating any ticket by:
Telling the truth, being very courteous (but not sucking up), apologize to the officer, acting VERY pissed at yourself, and saying sir, officer, please, thank you, etc.
I've gotten pulled over probably two or three times in the past year, every time with my V1 in plain sight, and I got off with nothing but a verbal warning every time. When I got pulled over, BTW, it was from instant-on. Even the mighty V1 can't detect instant-on!!!
