An American Tourist Navigating Irish Roads

John, a traveler from New York, rented a car at Dublin Airport for a scenic road trip across the countryside. He struggled initially with manual gear shifting using his left hand.

On his first day, he misjudged a rural narrow road and nearly scraped a stone wall while trying to adjust his speed from miles to kilometers.

After pulling over to recalibrate his mindset and focusing strictly on the km/h road signs, he adapted comfortably to the left-hand traffic flow.
