How could you not tell that car you were tailgating was a cop?

Whenever I see a thread about driving or parking I’m tempted to start a thread Driving in Thailand. A message here reminded me of an incident engraved in my memory since the 1990’s.

There are two northbound lanes on the Asia Highway; I was traveling about 70 mph in the fast lane passing a truck doing about 60 mph. Glancing in the mirror I see two cars approaching rapidly, though it’s hard to judge exactly how rapidly. I consider slowing down, so that I can get behind the truck, put my tail between my legs, and move into the slow lane.

Before I have time to react, both cars are upon us. One takes the left dirt shoulder, the other the narrow right shoulder; they pass the truck and myself simultaneously. Within a few seconds they’re out of sight in the distance ahead. They must have been going at least 120 mph (though perhaps they slowed down to 110 mph or so at the time they passed us in the shoulders).

I have lots of unbelievable driving stories from Thailand, but this one may have astounded me most.

(ETA: Yes “mph” not “kph”. We use “kph” in the Kingdom, but I’ve converted.)
