Cycle-able for whom though? A steeply-graded route favoured by an ultra-fit young rider on a lightweight road bike looking to test themselves to the max probably isn't the sort of route the average middle-aged person on a laden touring bike would want to attempt. We have no way of knowing the ability or motivation of those uploading their tracks.
That is true of every map and every guide ever produced.
Do you mean every map and guide aimed at cyclists?
It's certainly not true of maps aimed at car drivers. I don't think my car sat nav has ever sent me down an un-navigable route. Ditto for paper maps, pre sat nav.
Whereas Cycle Streets (for instance) sent me on a totally unsuitable track recently. At least in my opinion. In the spirit of making things better I edited the relevant section in OSM. And noticed that somebody else, after my edit, thinks it's that section is fine. Hey ho.
When it comes to sat nav I suppose cyclists are at least in one way similar to HGV drivers, in that what works for the "average" traveller might not work for us.

And there's the problem. Cycling will continue to be a minority activity if, as well as buying lots of special "gear", cyclists are also expected to pore over "sources", a number of them in fact, to work out something as simple as getting from this place to that place. I daresay a lot of the sort of cyclists who frequent this forums enjoy that sort of thing. I don't. I'd like to get on my bike and go there, guided by some sort of device, on a cycle friendly route. I can make a journey like that in my car.
