So below are a bunch of links that have some details about recent-ish autonomous and integrated driving technologies.
Each individually is interesting, Volvo working on mesh networks to provide "Linked" vehicles, google is developing autonomous vehicle decision making and route finding, the US Black Box bill makes data collection mandatory, and ubiquitous.
Basically what I am saying, is that TAKEN TOGETHER, all these technologies converge to create a world where in 10 years un-crashable, self driven vehicles are the norm in a crazy futuristic madness. It would be mostly electric, mostly quite boring etc.
But some of the implications are interesting.
1) How do you steal a car, when all the cars and all their owners know exactly where it is at any time?
2) If its almost impossible to crash, why bother with drink driving laws?
3) Fuck it, might as well let kids drive themselves to school....
