A co-worker remarked that the US should agree to take up the metric system in exchange for the UK to stop driving on the left. Nice plan, but some adjustment is needed. The UK isn't exactly metric friendly. The US will use metric if Japan stops driving on the left. With the UK, the US will agree to stop mangling the English language, and start mangling Spanish. If that isn't enough, the US will agree to continue putting down France, but will also continue buying all its great export products. The trouble is Australia and New Zealand. I don't think there is anything the US can do to persuade them to drive on the right side of the road.
