hitchhiking – Is it safe to hitchhike in Ireland?

I spent six months in Ireland, years ago when I was a student. I was in county Galway, out in the country. At the time it was safe to hitchhike and also the easiest way to get around because there were no train routes past Galway city in the west and many buses didn’t run everyday. This was back in 2004. I want to know if that is still the case. I’m hoping to plan a post-pandemic trip back there.
