Driving on the right ???
The biggest thing when I moved over here was FAR more life-threatening !!
I was used to the RED LIGHT being placed on MY side of the junction , and even in a foggy torrential downpour you knew where to stop . ( AT the red light )
I nearly killed my new American family on numerous occasions when I was first over here , traveling over 6-lanes of traffic to stop at the red light on the other side of the junction !!
