These trucks can and will put people out of work. Right now a large majority of the testing of autonomous vehicles is focused on "perfect environments". Yes, Google will say that test driving autonomous cars in San Francisco is far from a perfect environment; however, in a future where people are loosing their livelihoods, ways to hack autonomous vehicles will be explored, and I'm not talking about just hacking a vehicle CAN bus. All of these vehicles rely on technologies like radar, LIDAR, IR vision, etc. None of which are fool-proof and each of which could fall to very specific attacks. I hope that the auto manufacturers are considering this future. After all, we have technologies today like GNU Radio and the HackRF One which have brought what was once the domain of the nation state to the general public.
