Self driving is a very difficult (and expensive to develop) engineering challenge.. I think it might end up being cheaper (and thus more likely) that the "solution" will be a legal one rather than an engineering one: Self driving vehicles will have a light and/or klaxon on them, if you see or hear it, it will be your responsibility to get out of it's way. Thats how the issues with automobiles vs other road users was resolved in the 1920's. The impetus is there, corporations want more and more robots for everything.
