Speed isnt the problem, it is where your are doing the speed. Having lived on mainland Europe now for some time there is some difference between here and home. The motorways are mirror smooth, no bumps, potholes,etc (bar belgium, roads are terrible) and the speed limit is 130 kph. however it is not enforced and im always overtaken by cars doing 160+. and that is fine because speed here is acceptable, roads are perfect and drivers have excellent lane discipline.
However driving quickly around towns, school, and residental areas isnt. As mentioned above tho the Guards only go for the jammy spots where there will be easy targets. I live in Tivoli and am constantly checking my speed on both side of the dual carriage way because thye can be around. But do you ever see them doing speed checks around the schools?nope! That dual carriageway is a fairly low risk road for pedistrians, but is heavily monitored.
at the end of the day we have to remember its Ireland, if it means more moeny for our politicians to go on the lash and claim expenses they will do it, no matter how they dress it up to justify it.
