This is a very familiar situation for me and perhaps I can help . . . I was born in and learned to drive on a Caribbean Island where I drove stick-shift and on the left side of the road, on some pretty narrow winding streets. As life would have it, I started a travel company that produced all kinds of fun events for corporate groups to participate in on the island, one of which was a “road rally” (read navigated scavenger hunt). I also traveled frequently to the USA, (several times a month) and eventually became a US citizen. So my drill was . . . drive to the Caribbean airport on the left, fly to the USA, take airport shuttle to rental car lot, drive out on the right side of the road in the US and in reverse on the way back to the Caribbean. So to the dilemma. The majority of our road rally clients were American. To overcome this, we began every road rally with a briefing to teach people how to drive stick-shift on the opposite side. We’ve never had an accident in the 30 years we’ve done and still do this event. I called this "The Middle of the Road Theory (that always got a nervous giggle because the drivers thought I was kidding). I asked the soon to be drivers to picture themselves driving in the USA on a rural 2-lane road, traffic in each lane going in opposite directions. See that the DRIVER in his or her position in the car is in the MIDDLE of the road . . . the front-seat passenger is sitting curbside in the vehicle. The same principle will apply in Ireland. Also - when turning on to a main road from a side road or vice versa, driver immediately orients him/herself to the middle of the road. If the driver looks out his window and sees the curb, or the passenger looks out and sees a yellow line, make some immediate corrections (or scream bloody murder at the driver!) There is also a thing called a circle, or rotary, or round about. There’s another catch phrase for this . . . “the guy on the right is always right!” In other words, as you approach the round about in Ireland (the road always bleeds you into the round about from the left, and there is a car coming at you from the right - it has the right of way. So, Middle of the Road, and the guy on the right is always right. It’s what I’ve used for 40 plus years, and it’s never failed (except once with me - in St. Thomas, USVI, where they drive left hand drive (American) cars on the LEFT. That defeats everything said above. Other tips - when you, the driver, gets into the van in Ireland for the first time and find that someone has moved the steering wheel and pedals, don’t panic - the van is not on a GM recall list! Try the other side. When on that other side, you may find there’s a stick in between the two front seats . . . it is not a comforter to be stroked in times of stress . . . just as the third pedal on the floor is NOT the parking brake, but when used in concert with the stick, will preserve the life of the transmission. Finally, if still concerned, before starting out, place 2 ladies in the back seat . . . if you the driver so much as steps over the line, their screams . . . Have fun . . . Ireland’s a beautiful country.
