You shall not pass!

When it’s a nice country drive kinda day, why not frustrate other drivers along the way.  For instance, when you’re driving on a single track road and a double yellow line appears you should drop your travel velocity 10 mph under the speed limit. Hopefully, the double yellow stripe is long allowing you to build a nice caravan of cars. However, once the line breaks and allows other to pass, give it some gas. This will cause maximum frustration for the drivers behind you. Repeat this process until you are rammed from behind or arrive at your destination.
