Those individual workers hurt the project and the community around it by setting the precedent that you need to create your own competing product to verify that bugs can be fixed without PhD research.
Nobody should be harassed over their open source project, but that doesn't mean actions don't trigger reactions.
We have not automated driving. Phoenix is step one but there are parts of the world that get weather other than sunshine. Yeah those cars are cool, but the roads in Phoenix are better than any other major city in the US, the weather is binary, sun or rain, the city is modern, and the stop lights communicate with audi (I think its audi) cars and you can see when it's going to turn green on the instrument display. Phoenix is the absolute ideal place for self-driving cars. Again, its a great achievement. They are doing great work, but I think it's a stretch to make the general statement that we've automated driving.
