Make sure you get an automatic gearbox - it will make it so much easier for you with the controls. Read up on and stick to the rules. Take things easy - most people will realise you are either lost or unsure and make allowances. You may find roundabouts tricky - I found your equivalent, the 4 way way stop, took some getting used to. Always stop for a red light - whichever way you are turning.Other than that at least you are driving in the best place with the least cars and most couteous drivers - in my experience anyway.
Good luck and keep safe. Let me know if you come south of the border into NW England so I can stay off the road...;-)
