Re driving on the left in the US Virgin Islands, a reader in Scandinavia writes:

In Sweden, where I live now, they used to have left-hand drive roads and right-hand drive cars, like in St. Thomas now. They decided to change it in 1967. They decreed that on a certain day at 3pm every drive would stop their car and wait for one hour. At the end of that hour they would pull out onto the road – into the right-hand lane – and continue driving. There were a few crashes caused by the “unplugged” segment of society, but overall it went well.
My mother-in-law remembers the old driving days fondly. She said it was *real* easy to parallel park.

Obama needs to pull something like this. Let’s go all-metric on the second Wednesday in March. Perhaps as a condition of the auto bailout.

[UPDATE: The Swedes respond. From Hans:

Your Scandinavian source has gotten the “p.m.” wrong. I’m not sure of the exact hour, but it was definitely a.m., on a slow Sunday morning, September 3, 1967. I was nine years old at the time.

And Lars:

Of course it was at 3AM, when most decent citizens are safely in bed.]
