Not really a fair comparison, considering some of these countries are much larger than the others, and some of them have serious mountain ranges that prohibit the development.. of further networks.

For example, France is 18x larger than Belgium. Everything else being equal, you can't expect a larger country with more rural area to be as developed in public transportation networks as a smaller country.

Tradition. Red is the most easily/quickly recognized color, so it was assigned as "Stop". Green is opposite red on the color wheel, so it was assigned "Go". Yellow is in between those two and is also highly recognized, so it was assigned "caution - changing to stop soon".

Colorblind people CAN drive.

First off, there are different types of color-blindness, and not all of those interfere with interpreting the signals.

Also, stoplights are standardized so red is at the top & green is on the bottom. For horizontal lights, red is always on the left and green is always on the right.
