DON'T DRIVE IN THE LEFT LANE.
DON'T DRIVE IN THE RIGHT LANE.

Some pet peeves when driving on the highway:

The left lane should be for passing if you can manage it. Leave it open for those idiots who are always running late.
The right lane should be for entering and exiting the highway, or for slow moving traffic. Really, get out of the way there too!

People who drive faster than me are jerks.
People who drive slower than me are idiots.
People who drive the same speed as me are really the worst of all.
