People who can't drive

Okay, I know I'm a really frustrating driver because I go five over the speed limit like it's my religion.  However, at least I know how to follow traffic rules.  Two instances are forcing me to make this post. 

Number one.  Because of heavy traffic to malls and such, the people who design the roads within these areas usually make it to where the incoming traffic doesn't stop because if they did, traffic would back into the main intersection.  SO PAY ATTENTION.  If there's no stop sign- KEEP IT MOVING.

Number two.  I was behind a car in the turning lane to get on the interstate.  The light was green.  They stopped because of someone coming towards the interstate from the other direction.  There was plenty of time for me and probably a caravan of other cars to make it but this person stopped.  The person coming got in their turning lane to get on the interstate in a separate lane from the one I would have been in had the car in front of me learned to drive.  Instead, we had to wait for literally four minutes while an onslaught of traffic went by.  Then the light turned yellow... the car in front of me went at the last second of the yellow light and then I got to wait for the whole cycle to repeat.
