Just to follow up, I regularly see examples of bad driving in Ireland. However, the pieces about the cost of getting your license and fuelling/insuring a car are higher here, so maybe people do value their permission to drive more highly than in the US.
I've also looked at the Wikipedia List of countries by traffic-related death rate, and while the UK and Ireland have 2.6 and 3.0 deaths respectively per 100,000 inhabitants, the US has 14.2 (figures are from 2021 or 2022). For perspective, nine of the ten highest figures are from Africa and are all over 30.
