These seem work a lot like "bidirectional single lane with passing places" (mountain or very low traffic country roads). Except that you pass by pulling in behind a bike. It seems to me that it relies a lot on people understanding how they work. If most people have experience with the "passing place" version, these would work. If they don't, it would seem like they would need a lot of user education. Where I live, I almost never encountered a passing place road and they always made me very nervous when I did.
