Wasn't meant to be an exhaustive list, I am sure there are additions. It's just what I use, personally. I have a friend who rides with one of those flags on a bendy stick (that would drive me nuts) and now there are those lights that actually shine "lanes" on the road, too. I'm also not sure, other than an air horn, what one could add that would impact the behavior of drivers, but I would be interested. Personally, I just assume drivers range from clueless to hostile and it keeps me alive.
