Yep. Its kind of crazy how kids do this stuff, film and post it on social media, and feel they'll never get in trouble. I'm thinking they aren't very bright.
Waymo is owned by Google. I have to believe they will go after these kids to send a message and keep this from becoming a trend for their robo-taxis.
I'm pretty sure Google has the money and sway to make sure city officials go after them if the city doesn't to it already.
