Where people tend to obey the law.
;-)
Except that the law also says that lower traffic should keep to the right. If the flow of traffic is faster than you, even if you are at the limit, you should not be in the left lane. If you are not passing anyone, you shouldn't be in that lane. Slow drivers cause an unnatural traffic flow and that leads to accidents.
And as an old driver instructor was said, "It doesn't matter who's right if you're dead."
