GPS is more then accurate enough that is not the problem.
Core parts of the self driving car are the information gathering sensors and the software that handles the information correct. There is still more testing needed, also there would be a need to fundamentally change the law regarding car driving (and probaly car insurance).
Imagine a "bug".
1. exactly sensors can work offline.
2. a bug like in winxp? however it's impossible that the bug be synchronized among all autodrives (tm, (c), (r)).
3. Imagine a bug in nuclear plants... or traffic lightning, or... autodrive (tm, (c), (r)) is less dangerous...
1. GPS is not a sensor. And there are no "online sensors" used
2. I dont think you understand what i said.
3. No need to imagine, already happened.
Bugs will be important regarding driving and insurance.
gps is a sensor, it sense the position of global position satellites. other sensors are movement detection, temperature etc etc...
sensor sense reality into data (1,0). sensors are gateway to digitization.
there aren't that many pasterns of behavior (or event) in the road... (I mean in trillion)...
You are right. I was wrong in my explanation.
What i meant to say is that gps isnt used as a selfdriving sensor like infrared light and radio waves.
Gps shows the car which way to take. The other sensors and the processing software will drive the car.
It is sometimes annoying to not talk in your mother tongue.
*edit
Regarding your last sentence.
Every single human is an infinite amount of events
