Totally understand where you are coming from, but that is a great way to get killed. Control your temper. Remember motorcycle always loses to car.
Yup! And guess what, this will not be the last time it will happen either, so be prepared.
Try using your horn next time to get their attention and let them know thay screwed up, and try anticipating a little better on your part. If you see somebody on the cell phone, expect the worse case scenario.
Ironically, this exact scenario happened to me. I guy moved into my lane without using any turn signals so I hit my horn, but my horn didn't work! WTF...so I had to swerve toward the left and then slow down to let that guy talking on his cell phone in. He was totally oblivious to what was going on and I couldn't get his attention because my damn horn didn't work.
I love using my horn, and I let a perfect opportunity to scare the daylights out of some driver not paying attention get away. Yes, I bait vehicles, makes the ride home from work a lot more fun.
