This just looks like obviously 11.5 :1:1 to me, the slant would be totally wrong for 7s. I had to check back your comment to be sure you were really talking about these 1s as looking like 7s :)
But this thread reminds me of when I lived in Canada for a while (coming from France) and I did misread numbers very often, which was totally unexpected to me. Yes, 7s and 1s looks very different between Canada (and the US I guess) and France (and probably the rest of Europe).
I haven't had this problem with Belgium though I'm not surprised if the standard here had been chosen to be the same as in France.
They might be obvious ones in the context of this one person. But they are trivially not obvious next to someone who writes one like "|" and then seven is just "|" with any sort of hat. Your slant heuristic immediately fails.
It's "obvious" because 7 is always slanted here. But I know it's not the case in North America and I have a good experience on how numbers can be misinterpreted, as I said.
I was just saying it was obvious to me and it even takes effort to see how they could be misinterpreted. But I know they can be.
