I actually shudder at the idea of programming a heavy duty object like a car, to predict pedestrian behaviour (to avoid collision/injury). Can we guarantee this for small drones for dropping packages and flying around in our city skies without hurting someone?

I do have specific opinion of Google search engine --it scours only web pages and documents placed on the open Internet. I realize that Google has done some neat stuff for automatic semantic ranking/matching. It doesn't dig into proprietary meaty databases --that have their own software platforms, search engines, firewalls and also may require (hefty) access log-in fees. Google cannot help you in a few minutes to direct you to the right database(s) out of several similar databases if you don't know the scope/general coverage of a database. The sad thing is not everything has been digitized and most likely never will be. There is still a decent amount of brand new hard copy content that is not digitized -- since publishers have a vested interest financially while they also run their fee-based digital services/products division.
