I've been known to feel around for braille signs on bathrooms and the like.
Braille signs on building doors? Sure, makes sense.
But street signs? Half the time I'm not even aware of their physical
existence. When I'm out walking, if something isn't directly in front of me,
or right next to me, or producing sound, I'm not even aware of it.
With my cane, I effectively have about 1.5 m (5 feet) of "visibility" in front
of me, with a bit of clearance on either side. And even if I'm aware that
a street sign exists, I'm not likely to go feel it up. It's probably just
a thoroughly uninteresting sheet of metal on a pole.
I'd be far more likely to check out the bushes and foliage
near the sidewalk. Note I have no sight at all.
For someone with more sight than I have, maybe braille street signs make
sense, though I'm still kind of doubtful.
