Some sting for these two doughnuts with a €3.5k fine each and a limiter to be fitted to their cars to a max of 100km per hour. I think the limiter is a bit of an overkill, it actually could be dangerous in some situations such as safe overtaking and such but the fine might deter others in future. The Garda in question must have had a real bee in his bonnet about catching these lads as he tracked them down via facebook.
I know a few people living outside Killarney and they basically have to say goodbye to sleep whenever the lakes are on because of these clowns. I've no problem with drifting or doing donuts, I've been known to try it once of twice myself but not on a public road ffs.
