11. People that come to a complete stop to take a right turn. What. The. F***.
(Obviously when you're driving on the right hand side of the road.)
People not making turns on red when it specifically says they can as long as people aren't walking across. These signs mean the same thing:
12. Pulling out on to on coming traffic and then driving really slowly, I've yet to fathom why people do this and have started beeping them
That is actually illegal, if you enter into traffic you must be able to do so without inhibiting the flow of traffic. My first accident happened because someone did this without looking left before turning out.
What gets me more is people who turn into the wrong lane, sure some people do it so they can make a turn without blocking traffic, but all forms of this wrong. Making a left turn from the left lane, you better end up in the left lane, because I will keep you in it if we are turning onto a three lane road from a double left lane. Same with turning right, go into the right lane, not the center or left lanes.
