But you could say it wasn't you and not say who it was and plea the 5th. Pretty much your in the clear and your buddy needs to lawyer up or something cause thats ridiculous.Also the real thing you should be happy about is not getting racing tickets.

How so? He got caught driving like a douche nozzle, and deserved the ticket he got. Period.

To answer a few of the OP's questions:
Yes, radar will work while in motion. Most police traffic vehicles these days have dash mounted units built into the car. Beside that, even if he didn't actually clock you on radar, as long as he is a radar certified officer, he can use other, manual methods of calculating your speed. End of story. Being that the officer quite clearly got your tag number, and witnessed you in the act, he CAN come back and write you a ticket, like redGT said, as long as it's within the statue of limitations for whatever jurisdiction he's under.
