I got the feeling that man had been accosted many times by angry locals and I may have been the first to give a word of encouragement, he was very polite after the initial tension wore away and he felt my shared enthusiasm. He must have been one of the early engineers, I had never seen or heard the name waymo but I was aware google had been competing in the level 1/2 dessert tests.
The man was very friendly and i was surprised how his behavior must be a reflection of society's view towards technical automation. Seeing the videos of people kicking food delivery robots and now my own tendency to flip off elon musks tesla cameras all these years later I am starting to get why he was nervous.
Cheers to the future I suppose, but hopefully the future has less cars and more walkable cities.
