#3: What are they teaching in mathematics today?

Obviously it's not how to count to 2.
Couldn't believe how many cars with single occupants I saw in the car pool lane today.
And for you people in the BMWs, your EGO doesn't count as a 2nd occupant.

#2: You can't be in that much of a hurry

Twice in one month, I was cut off in the right lane by a car that then cut off the car that was previously in front of them in the left lane, only to IMMEDIATELY jump into the turn lane and make a left turn.
REALLY??
Seriously, nobody is in that much of a hurry.

#1 Late Merging Cars

This is for the assholes that can obviously see that the lane is ending and traffic is merging, but they rush up as far as they can before forcing their way into line.

The CA law states: A driver entering a roadway from a roadway that is intended for and constructed as a merging roadway, and is plainly marked at the intersection with the appropriate merge signs, shall yield the right-of-way to traffic upon the roadway that is so close as to constitute an immediate hazard and shall adjust their speed to enable them to merge safely with through traffic.

In plain English: It's not my responsibility to get out of your way if I'm already in the lane. I don't have to yield to you, and I'm only doing so cause I don't want to sit there for hours waiting for the cops to come along and write you a ticket and, much later, for your insurance company to fix my car.
