inky: Only about 28% of the world’s total road distance carries traffic on the left (blue), with 72% on the right (red), according to Wikipedia. I had no idea we left-siders were so outnumbered. I wonder if this is merely a coincidence: Today, only four European countries drive on the left: Cyprus, Ireland, Malta and the United Kingdom. None shares a physical border with a country that drives on the right and all were once part of the British Empire. I’ve always thought there was something odd about right-hand traffic, but I just couldn’t put my finger on it. Then I read this: Research in 1969 by J. J. Leeming showed countries driving on the left have a lower collision rate than countries driving on the right. It has been suggested this is partly because humans are more commonly right-eye dominant than left-eye dominant. I was just wondering which side you drive on in the Channel tunnel. Hmmm.  Click for high-res photo
