Regarding your last podcast, and the origins of autonomous vehicle, guerilla tactics played great part in the US conflict in Iraq and Afghanistan.
Many in the military still die from improvised explosive devices, IED, from unexploded ordnance guerillas recover and use against trucks.
This is the reason DARPA sponsored a contest in 2005: trucks are expendable but people, not so much.
Well, image if, instead of invading Iraq and Afghanistan, just half that cash was put into autonomous vehicles. We'd all be flying around in them by now.
