"...just driving on the right side of the road for pretty much the whole world. Why on Earth does the UK still drive on the wrong side of the road?"

So 35% of the world drives on the left. Take China out of the mix and we have a majority. I forgot Pakistan, Indonesia and Malaysia. That's a lot of "wrong" people. I suppose "whole world" is in the sense of Trump's America First and sod the rest and of your very stupidly-titled "World Series" rounders contest.
