I suspect that riders pretty much blank out standard road signs: most are obviously meant for vehicular traffic and do not apply to them, and are at a height that is not where they are generally looking.I'm advocating for using a different sign at that location, because the currently used sign is interpreted as a sharp corner. Which the riders interpret correctly, but if the road is also not up to standards of normal roads, you aren't made aware of this.
We already have multiple different types of signs for riders, so maybe there's already one that says the road itself is dangerous.
So this would have to be some kind of mobile signage, flashing lights or other high visibility feature, sufficiently rare that riders don't come with time to ignore them as routine, and yet not something that riders become so dependent upon that they are at a greater risk in lower budget races where they are not present. I'm not saying that there could not be a place for them, but they are only at best a very partial solution.
