Just back from Spain, and drove there for the first time (I got my full driving licence in Ireland). Nor once I got confused about what side of the road I should be driving, broke the speed limit or did something I could regret. 108 people died in the road in Spain during the Easter holidays (from 3 pm Friday 7th to 0 am Monday 17th), 48% of the people that died were not wearing seat belts, 35 of the drivers that died where not wearing seat belts. Roads are a bit better in Spain than in Ireland, but it's common sense, paying attention to the road, that will save your live, not restrictions on the car.
I didn't meet any speed check on the way from Dublin to Cork on Monday, neither on the way up the week before that. I haven't actually meet any garda in the road since I am driving ( a year now), except for those checking my road taxes. Law should be enforce not to make money, but to "educate" people. Breaking the law has fatal consequences. Someone can die if you don't drive safely. Could you live with that for the rest of your life? I know I couldn't.
