> We've had computers and sensors powerful enough for decades, only Google have all of that maps data, polished again and again by android users using maps (and now Ingress) to make it more reliable. Of what relevance is Google's map data (which they buy from vendors)? Google's map data doesn't tell the car if a pedestrian or another car or a fire hydrant is where it is about to go. The car has to figure that out all…
You don't quite understand the scale at which Google operates. What they're essentially doing is building a 3D model of the entire world , using their own data (did you think those Street View cars were just taking pretty pictures?). By comparing the real world against the model, they'll be instantly able to distinguish between the fire hydrant (which was there yesterday) and the pedestrian (who wasn't). No algorithm…
Street View is YEARS out of date in most major international cities and doesn't exist in the majority of smaller cities. It would be dangerous borderline criminal for a self-driving car to be relying on it for anything important.
