The Irish Examiner reports today that foreign drivers and holders of non-Irish licenses are "costing the state €2m in unpaid fines". I guess this works both ways. I know I once benefited when I was pulled over for speeding (yes, me, who never stops going on about speeding) on the Taconic Parkway. I was doing 67 in a 55MPH zone {it was near the top of the road and there wasn't another soul on the road).
I was driving a rental and when I showed the cop my Irish drivers license, he just handed it back to me and said, "Please slow down", which I duly did.
