Why would color blind people struggle with this sign? There are no similar looking signs which mean something different.
The closest one would be this one:
And any color blind person is able to distinguish those two easily.
I see how it can be confusing for someone not used to it but for anyone who grew up in a country where this is the default it is perfectly understandable.
Accessibility needs to be universal. There may not be other signs like that in a particular city or country, but the rest of the world uses a line through “do not” signs.
Even a child could understand what it means, compared to different random coloured edge markings. And that’s exactly the point.

your defaultism is showing. In fact most of the world uses a white sign with red border to mean a prohibition.
and in fact children need to be taught what traffic signs mean all over the world, they don’t magically know it
That’s crazy.
Like, this sign means maximum speed limit, not “don’t go 20”…
To me, it’s illogical.
Like, how on earth would the right be better than the left in explaining that bikes are not allowed?
The use of a red border needs to be consistent, if it were to mean prohibition. Yet, it’s not 🧐
The thick line on the left covers up part of the bike, making the sign overall harder to read.
Also, the red border on the 20 does make sense, as it’s a speed prohibition on going over 20.
