... you drive on the right side of the car...
...and the left side of the road.
The change did take some getting used to at first that's for sure. But it actually helped that we didn't have a car the first month or two here. Riding the bus and going in other people's cars allowed me to get a sense for the car, the road, the rules of the road and the location of things.
Now I feel as if I've been driving this way most of my life. In fact, the other day I tried to envision the roads and cars back home and got worried that I wouldn't remember how to do THAT when I go back. Weird.
