On his twitter account @righttobikeit
He is a knob that deliberately goes out to seek trouble. He also has double standards, cycled half the the way to Carrigaline on the wrong side of the road, the other half he under took the traffic. Neither of these of course count as bad road etiquette.
I know two people that have had run ins with him in the vicinity of Carrigaline, and you can see from his Twitter account that he relishes the argument at the side of the road. One day he will try it on with a nut job and he’ll be in a bit of bother then!
