Those who abuse others on the roads.

It has become more and more obvious to me that there are a lot of assholes driving on the roads and highways near where I live. I can no longer speak for Ireland as I have been away for a few years and every year I do go back it has changed a lot.
But in my everyday dealings with other drivers I have found a serious level of asshole driving. Those who are desperate to get past you even though afterwards they will be only a car length in front of you. Everyday at regular intervals you have police parked in at the side of the highway monitoring the speed people are doing. So of course you get this speed well over the limit until a cop is seen then you have this brake down to legal speed and so you have this stop start stuff going on. People always seem to tailgate so close in fact that you cant see their headlights and then last Friday, my personal pet piss off peeve when I had complete right of way making a sweeping downhill slight left this dick completely cut across me and I had to break orelse I would have clipped the back of him and to make matters worse his passenger waving at me in an unfriendly almost taunting manner as if to say screw you.
