What I'm curious about is how will different algorithms from different manufacturers all react to each other? Is there a standard set of rules that Google/Tesla/etc are all working together on? i.e. What happens when one mfgr's car does something mfgr B's car doesn't recognize or "agree" to?
Further, if the rules states "minimum distance is 3 car lengths" then how does it know when the brakes have worn out and 3 car lengths is no longer a safe distance? Is the onus on the car or the owner at that point? Will the car just refuse to turn on if it senses that work needs to be done?
What happens when a tire blows and the car goes into a spin? (I've seen this a number of times). Has Google's autonomous car blown a tire at highway speeds?
