I'm a left hand driver (UK) with experience of driver both RH and LH drive cars abroad.

The dangerous times are when you're not concentrating on the fact that you're on the wrong side. When you first pull out at the beginning of a journey. When you pull off a motorway having "cruised" for an hour. After turning off a road with little traffic.

To this end, do as much as you can to reinforce the unfamiliarity of it all (the worst thing is taking a UK car to France - if you get in through the "wrong" door, you're instantly reminded to do things differently).

So don't (IMHO) get an automatic (unless you have a weak left wrist!). Having to change gear with the "wrong" hand will constantly remind you that it's all a bit different!

Safe driving...
