What really gets me is city drivers that don't know how to merge or yield!! You're following this nimrod heading to a merge lane and what does he/she do?? Slam on the breaks almost causing a pile up!! I don't understand what is so dang hard about the concept of merging.....it's just going with the flow of traffic people!! That's it!!
especially whenthe point that they decide to stop/slow down happens to directly coincide with you shoulder checking to see if it is clear to merge.
