I still get irritated by other drivers but I TRY to just let it go. I drive alot for my job and see alot of idiots. If I reacted to all of them I would never get anything done.
I stress that I do try to let it go but somedays I let them know my displeasure with their actions.
In regards to the freeway and entrance ramps: I will always try to move to the lane away from the ramp so that the person getting on can merge knowing that I am not going to challange them. I usually run in the furthest right lane on a 3-4 lane freeway as the clowns like to run fast in the passing lane. I tend to fly under the radar. Cops generally don't pay much attention to the car in the "slow" lane.
I did the flash to pass in the BMW the other night to a guy who was running 10 mile UNDER the limit on a 2 lane road. Cars were piling up behind us so I looked for a clear shot and gave it heck. Problem is the BMW is an automatic. I hammered the brake pedal thinking it was the clutch as I had been in the 911 the day before for several hours and earlier the same day. DOH!!!!!!!! My wife thought I lost my mind. Fortunately for me, the guy that was behind us just a moment before had turned into a driveway.
As I looked back the guy had no clue as cars were trying to pass him and he was just toodling along, left arm on the wheel,gangster lean going on.(BTW_He appeared to be a middle aged guy, not some old fart that didn't have a clue he was holding up other people.)
