Similarly the strange US habit of text on the ground being written bottom to top. I get what they intended, but I don’t get why, then they first saw the effect, they didn’t laugh and realize it didn’t work.
The text on the ground is written bottom up because the bottom is seen earlier in a moving vehicle, making reading it easier when in motion as the ‘bottom’ word is ‘first’ to the driver. This is more noticeable in cars that are lower to the ground, and they continue to use it because it does work.
Not all applications need to take vehicle motion into consideration, but they keep it for consistency.

I know why they did it, as I said. It’s obvious. But it doesn’t really pay off in practice.
