it isn’t though. you don’t need cars to learn red means stop, we literally had miniature roads, crossing and signs at my pre-school (or whatever it’s called in English, the one you go at age 3 till 6, you start school at 6).
Stop sign is red, pedestrian crossing are just red - stop, green - go. you learn that from a very young age so the association is natural.
Also, just to be clear, I didn’t say redlist is good, just that it’s less stupid than blacklist.
