Last night, 2AM to be exact ,North bound 5 freeway 20 miles from LA, I got a speeding ticket doing 79 mph on 65 mph limit. The freeway way was virtually empty I thought I was doing 70ish on the 2nd lane. From downhill I noticed the CHiPs flashing at me. I slowed down, still the officer got me off to the next exit.

Please let me know what I should have done and should do.
1. Former officer friend of mine advised me never to play a smart a$$ in this situation, immediately apolozise and ask for his/her mercy. That's exactly what I did. I told him that I thought I was doing close to 70 mph. (Well admission of guilt I know it doesn't stand well on court.)
2. Officer asked if I spotted him on the top of the hill which I denied. He also advised that IN A NEW CAR(05 X5) ESPECIALLY IN DOWNHILL IT IS LIKELY NOT NOTICE YOU ARE SPEEDING.

Does cops profile Bimmers during their speed trap operation?
My other ticket was from my other BMW, the cop metioned some about the car while I wasn't the only one who was speeding. I will be going to the court to take a chance of him not showing, last time it didn't work because the sheriff station was right next to the court house.

Any advise? Perhaps any gadges to deter this event?
I am a thirty something man, I don't exactly have cleavage to entice the officer to give up his right to issue tickets.
