Per capita income doesn't reveal the actual income disparity. SF wasn't always expensive city to live. It was in fact quite the opposite. Last several decades have made the city inhospitable for the economically vulnerable population. Instead of looking at the per capita GDP, you should see the income distribution in the city. The median household income is $126,000 which is not a livable wage in the city for a family. The recent poverty rate is ~10%.

My perception is that, people were partying & were drunk. The Waymo vehicle likely was just passing through and probably got stuck. People simply took out their pent up frustration on it. It's nothing more than that.
