Several times. Ticket for running 4 way stop. Once touring on Hwy 1 in California around Watsonville, it turns into a freeway for 5 miles. I decided to 'go for it.' Car was honking at me and I ignored it... kept honking and I finally turned around and it was a CA Hwy Patrol. Told me to get off and go west to the ocean.... really good camping there. Was really nice to me.
I finally asked a retired cop how do you keep from getting pulled over.. said "if you run a stop sign or something and see the cop sitting off to the side waiting on cars to run the stop, hold up 4 fingers." It's a 10-4 sign, meaning everything is good. The cop will think you are another cop, and cops don't want to pull over other cops. It's worked 4 times for me.... although the last time it was a sheriff and he started up and followed me for a couple miles and gave me a dirty look.
