Oh man, the vulnerabilities of using likely untrustable networked sensors for safety critical operations boggle the mind. While the sensors theoretically could be made trustable, for some level of trust, I would be very wary of trusting at the level of safety critical application. Inadvertent vulnerabilities and attacks by malicious actors would be catastrophic.
My prediction: "crashdummy" will eclipse "heartbleed" and "shellshock"!
Though, with many self-driving cars perhaps the sensors on each could share info, thereby mapping a larger (if not, endless) area.
