I like to tell my British/Aussie/Kiwi friends that we Americans drive on the right side of the road, while they drive on the left wrong side. Well, in every single country we’ve hit since we started this trip, people drive on the left. After five long months of bus-riding and car-renting, the unthinkable happened. I got used to it. It started to seem normal. Left seemed… right.

When I went to see The Muppets in Singapore, I cringed at a shot of a Greyhound bus cruising toward L.A. Instinctively, I wanted to yell, “Watch out, you’re on the wrong side of the road!” The indoctrination was complete.

Noooooo!

And then came Cambodia, Asia’s odd man out in so many ways. Suddenly, the cars are back on the right side, and I’m trying to remember which way to look before crossing the street.

Ultimately, it’s like riding a bike, and it all came back to me by the time I rode a bike (along the Mekong). But look out: Thailand is next, with another directional swap. Maybe by the end of this trip, we’ll be ambi-lane-strous.

Or we'll just have '80s Robot drive us around.
