2009, humans in US:
185 crashes per 100 million VMT
1.13 deaths per 100 million VMT
all weather, incl. intoxication, bad luck, etc.
current google car tech relies on brute forcing visual mapping, breaks down in snow.
self-driving cars are controlled by software, written by humans, riddled with bugs. see Nest on how awesome this works for physical stuff. the aircraft industry has the correct coding practices, NONE of which are being applied by the current research teams. multi-redundant systems in play, with even more training for the operator. competing with human drivers is really hard. a shit ton of signal processing, etc. going on. all this techy-BS is belittling the awesomeness of the human brain and central nervous system.
