I think most people I know in the cycling community actually is quite aware. But we're enthusiasts. Daily someone post a picture of some crack in the frame and people discuss if it's into the carbon or only superficial. A common problem I've seen, where it's invisible damage, is rust on the handlebars below the bar tape. Especially bikes used on indoor rides during the winter where you sweat much more than on an outdoor ride, corroding the material below. But honestly, I don't think this is where cyclists should be the most concerned. Separate infrastructure, lower speeds of passing cars etc will do a hundred times more in reducing risks and injuries.
