Do you know anything about usability? And relative cultural meanings?

About 1.5 billion people drive on left (India, UK, Australia, Japan, Singapore, Malaysia....). Road sign "to the left" has VERY important meaning for big part of globe. Some people travel a lot and change left/right driving a few times every month..

But perhaps Beyonce songs and American pop culture, should be part of driving exams globally! So everyone can parse your "funny" jokes.
