Isn't this exactly the point? You look at this the analytical way, decide the bus doesn't have enough detail to be a realistic representation and stop there, maybe looking around for other clues. A very good example imo. Sure, the bus could be in reverse, but it could also be a British bus driving in the US. Or we could be looking at a reflection of the bus. Or we could be looking at the reflection of a British bus going in reverse. This is not about determining the direction with 100% certainty. This is about having a clue at all which you can justify, which adults mostly don't.
