Earlier quoted context omitted.
That bus example is one of the dumbest things I've ever seen. Spoiler follows: The solution is supposedly that in countries where you drive on the right-hand side of the road, children immediately deduce that the bus is traveling to the left. This seems nonsensical to me because it's not even clear the bus is on a road, or it it is, that it's on the far side of the road. As far as I can tell, the bus is in a dirt fie…
The rationale they provide is that you can't see the door to the bus. So we are looking at the driver's side of the bus. Ignore "Which was is the bus going?" and instead ask "Which side is the front of the bus?" And, knowing that we are looking at the driver's side because of the absence of doors, the answer depends on which side of the road the bus is designed to be driven on.
I mean I can't even tell. Because no bus looks the way the bus in the image looks.
I've never in my life seen a bus where the windshield was the same size and shape as the back window. Never in my life seen a bus that didn't have brake lights or turn signals. And so forth.
In other words, there are so many things wrong with the "bus" that I don't know why you'd assume that if the "artist" had drawn it from the other side they would have bothered to include a door.
