Poor design. If you were colour blind, that sign would be very confusing.
No it wouldn’t. That border shape only exists in red for prohibitions. Even if you were colour blind you could see the border. There is no other sign you could mix it up with.
The strikethrough is in use for a different purpose, to cancel a previous sign (i.e. end of the bike lane).
There is a reason it’s red though, so it stands out. You might not have the time/attention available to clock if the sign has a circle around it if you’re color blind. You see a circle sign with a bike. You have to look extra hard to see there’s another (possibly faint to you) circle on the sign.
That said, I’m not colorblind and forget exactly how that works so maybe the circle actually looks black to them or something.
