Sadly not a surprising event down here .
I've lived here for 12 years now and witness appalling standards of driving daily.
I'd suspect that he had decided to continue to the end of the "road" in the hope/belief that a space would be available to turn around. This would avoid the utterly terrifying prospect of having to reverse the car .....I'm certain that reversing was never included in the Irish driving test as almost every day I see drivers of all ages and sex just being completely overwhelmed when it comes to going backwards IN control. Only last Friday I encountered an oncoming Avensis ( staple farm hack ) on a very twisty single track road who expected me to reverse 80 yards to a passing place when there was one no more than 10 yards behind her. I actually offered to drive her car for her and was thoroughly entertained whilst watching her drive into hedges ,up onto verges and finally into a linear passing place at an angle of 60 degrees almost destroying a Rhododendron ....

County Kerry is also remotely populated and therefore many elderly drivers have to drive but are not , and never have been , that good at it . When following other cars the classic signs are , severe braking when any other vehicle approaches in other direction , inability or desire to travel faster than 20 mph , a flat cap or top of a perm where a head should be in the drivers seat , indicator deletion option ticked upon vehicle being ordered new and the total inability to acknowledge any courtesy shown to them at junctions etc.
Probably the worst driving I've ever encountered in all of my life .
