Yeah, but they have scheduled and registered driving instruction through school early on, which we don't, and until we do reform the instruction system (which they're talking about doing "once the backlog is cleared", like that'll happen anytime soon!) I don't think there's much can be done.
As for it not being hard to pass the test, ha! A friend of mine is currently learning, just got his second provisional, is the most careful and conscientious driver I know, never breaks the law, and has failed his test three times. I've sat with him I don't know how many times as he was driving the last two years, and I don't know what he's failing on, except that the testers are looking for the "perfect drive". He is perfectly competent and perfectly safe, but stupid things like stopping a little too close to or far from the car in front at lights, going a little too slowly down a narrow road with cars parked on both sides and a school emptying for the day have failed him his test.
Anyway, I should stop ranting. This has gone completely off-topic.
Basically though Les - you will need regular access to a car in order to learn to drive/get the experience needed to pass the test, so that will probably need to be one of your first priorities when you get here. Just some cheap banger like (or if you have one at the minute, bring it over, as the €1000 re-registration charge is probably less than you'd pay to get a semi-decent car here). Driving lessons are really expensive, and an hour once a week isn't enough to pass the test unless you're doing it for months.
Also, have your wife apply for her test *the second* she starts learning, as she's likely to have at least 6 months, if not a year to wait before she gets a test date.
