I imagine phones will serve that role eventually. GPS chip accuracy is improving constantly and could be accurate to within a foot in some phones in the next year [1]. Google Maps / Waze already do something similar with predicting traffic times based on phone data (and other sources). GPS accuracy currently may make an individual's location slightly harder, but path prediction may help. (And, of course there are privacy concerns to consider.)

So if you're homeless and can't afford a phone or if you forgot yours at home or if you got pickpocketed... you can expect to get hit by a self driving car?
