The Gardai in Cork are fairly relaxed so far. I've done 140 miles on it since I got my Boosted in January. I think theres a grey area around electronic skateboards and scooters etc. regarding road use. As long as you're careful and don't do the bollux they'll leave you alone (in Cork anyway). I imagine this will change as these things get more popular and cheaper and theres more people on the road.
