Good thing they aren’t on your roads then, being that you’re not American, and therefore not in either of the metropolitan areas they operate. They are on my roads however, I see them all the time. I see constant terrible driving from all kinds of people, but these things are patient and I don’t think I’ve personally seen one make a mistake.

By referring to their current stage of deployment as a public beta like it’s a bad thing you show a ton of ignorance on how testing cycles work as well. No amount of alpha testing would make these safe for broad deployment into real world scenarios that test designers can’t dream up. This is exactly the type of slow roll out that is required to get as much real experiences as possible to be programmed for.

I have no doubt these things aren’t perfect, but they are a lot better than an overworked and tired human being the wheel.
