I mentioned this earlier, but my reason for hating the "wavers" is that I once got to a 4 way stop after another car. After she insisted I go first(multiple waver), I took off and immediately got pulled over by a cop. When I explained to him that I went before the other car because of the waver, he chuckled and sent me on my way.
Negotiating a 4 way stop should be a mandatory part of the road test and if you wave somebody through, it should be an immediate failure.
Stupid wavers!
