Okay, this time the bump was really my mistake. I'm even ashamed to disclose completely what happened. But let's just say I was driving in the middle lane and wanted to turn right. I signaled right to move to the right lane first before the right turn came. There was a car in the right lane from behind which did not want me to move to the right lane and kept honking. So I let that car move ahead of me then moved to the right lane behind it. I speeded ahead to catch up with it, and yes that was my mistake, I admit it with a bit of shame. The right turn approached and I did not know if that care in front of me was turning right or going straight, I guess he signaled right but I can't remember now. Anyway, when I got right next to the right turn I discovered he was not turning right and he was going straight. Now here was my real mistake: I speeded ahead turning right yet something I was not expected happened, the car in front of me which did not turn right and was moving straight ahead stopped! That car stopped I guess due to traffic in front of it. I was honking all my way behind that car even before the right turn. I honked, moved forward and turned right bumping the car from its right side rear and my car from its front left side! It was my first time (and hopefully last) to bump my car from the front left side. Now I have my car bumped and scratched from the four corners (funny, but true).
Lesson: Never speed behind a car no matter how much it honked or annoyed you. This is childish behavior. I repeat, this is childish behavior and could cause your car to be scratched or worse yet might result in a serous accident. Don't go crazy when driving. Safety first.
