When i first time 35 years ago in Siberia saw an excavator driving itself toward me without driver, i was struck like by lightning and first moment attributed it to hangover. Next moment though i saw the driver walking along the road looking for mushrooms and understood that the deep tracks in the unpaved road are like rails so that the excavator just moves along these tracks. Couple years later (this time another part of the country - a low populated part of the St.Petersburg region) my friends who were vacationing in a remote village there saw one day a large tractor passing on its own through that village, and next day guys came asking whether anybody saw a tractor without driver - the guys were drinking and details of how the tractor got away weren't clear though ...
I can relate to how you felt. Even though I developed this myself, when I saw it running remotely with no one sitting inside for the first time, it felt magical and weird. This is going to save lives and look magical and that's too much fun to put off and do something else!
