Closest I know of to this scenario is someone who is deaf, but uses cochlear implants. He has ridden across Iowa on RAGBRAI multiple times. The biggest challenge is interacting with other riders in such a massive group(hearing 'on your left' or 'bike off' etc). He has a group he rides with and the person ahead uses hand motions to let him know about slowing or stopping up ahead and a mirror helps see those behind who are passing.


OP- very cool goals. No reason to think you couldnt safely tour. On highways, I often dont know about a car behind me until 100' away thru hearing. A mirror would pick up cars behind you much sooner than that.
