You have to decide which side the gas cap is on, and you only can observe the back side of the car. The answer given by the puzzler is to look which side the tailpipe is on, then the gas cap is on the other side. I got to wondering if today you even need to look at the tailpipe. First of all, for some reason a lot of cars these days have tailpipes on both sides. In taking some neighborhood walks I decided I could almost always tell just by noting the manufacturer of the car
- European cars have it on the right
- Japanese cars have it on the left
- American branded cars have it on the left, except for Ford, which seems to have it on the right
What do you think? Is my “just look at the brand” algorithm is as good as the “look at the tail pipe” version?
