Given the state of cybersecurity, the car goes wherever anyone with sufficient motivation wants it to go. Including into pedestrians. And, such a scenario could happen at the scale of a botnet swarm. In other words, hundreds of thousands of vehicles could be simultaneously hijacked.

"If you drive your own vehicle, it goes where you want it to go"

I think privacy conscious folks like yourself consistently overrate how much purchase this argument has. I am perfectly happy to forgo this in exchange for a sufficient increase in convenience / safety (for myself and others). This is not because I have been brainwashed by autonomous vehicle company propaganda, it is because I have different values and concerns.

So you mean to tell me that when I called a Waymo a few weeks ago at 1AM because I was drunk at a bar and wanted to go home, it was actually because my government and Google wanted me to go home?

Woah! This conspiracy goes deeper than I thought! Next you'll tell me that a taxi ride requires mutual consent between me, the taxi driver, and the dispatch company!
