If one is an unfortunate person from the country heading in the direction of Dublin Airport one's shock only begins with the "mad cow" roundabout, which seems to have been designed – I do not often quote Kevin Myers – to guarantee the maximum upset to the maximum number of people coming into and going out of Dublin. I have no idea which genius decided that so many major roads out of and into Dublin should all coincide in one inadequate junction. However, somebody did and I have a suspicion I know which Department took the decision to underinvest in that roundabout. It was probably not the Department of the Environment, Heritage and Local Government or the Department of Transport. I am sure the geniuses in the Department of Finance, who are not accountable to anybody, whose performance is not measured by anybody and who are not under any benchmark of any form, decided that the traffic expectations that are now the reality were unrealistic and decided we did not need what turned out to be needed.
