It's kinda funny how every 17-year-old kid complains about "bad drivers".  I guess I never moved past that phase.  I happen to drive quite a bit.  But I think that even if I drove 2 miles a day, I'd still find a million idiots.  That's just how I am.  So here are a few:
1.  People who would rather die than drive on those yellow striped areas (usually right before a left turn).  Instead of getting out of people's way, they slow down before they even enter the striped areas.  That makes me happy.  I understand the point of these stripes:  to deter people from driving there.  However, I think it's also to deter people from thinking that it's a lane.  I understand that.  I move past that.  And I drive there. 
2.  People who come to a complete stop at a red yield sign.  There are 2 types of yields:  yellow and red.  Yellow means slow down; red means stop, IF THERE ARE CARS COMING.  But it's a yield, not a stop.  You don't have to stop at a red yield sign if no one's coming.  That's why it's a yield. 
3.  People driving in the far-right lane on a major 3- or 4-lane highway, making it so that you can't enter the highway until they pass you.  This is normal, EXCEPT WHEN THERE'S NO TRAFFIC.  Yet some people feel the need to take up that right lane so that I can't get out onto the road.  I know "the book" says to only use the left lane for passing, but it turns out that not only is this rule rarely (if ever) enforced, there's also usually a middle lane meaning that you can not be in the "passing" lane but also not be in the "slow idiots" lane. 
I expect all people on earth to read and to follow this, making the roads and really the whole world a better place.  Amen. #travel
