We had heard that Ireland had the highest accident rate in western Europe but for some reason that didn't bother us, until we got in our tiny rental car & hit the road! Life altering to say the least, I aged 10 years from the airport to the hotel. We alternated between cursing & laughing so hard we could hardly breathe. Don't underestimate the learning curve of everything being opposite, even the gas guage works in reverse. We did have GPS, a few flaws with that were we had no idea what distance a kilometer or meter is so when instructed to turn in 250 meters we were at a real disadvantage. Also the streets are not clearly marked with standard signs, in standard places, like on a corner, like we're used to. The GPS spent more time "re-calculating" than anything else. We had also read that while the roadsides are beautiful they tend to be narrow & curvy, that was the biggest understatement of all! We had to back down a windy road until we came to a driveway to go in so a truck could pass us, another day a car had to back off a little bridge so we could pass. The highways are roomier but they have these things called "roundabouts", the name says it all! Now when all is said & done and we swore never to drive in another foreign country we were quite proud of overselves for not adding to the high accident stats!
