Nice trolling, don't know why you're at 2, as you reference the same article twice and when looking at its contents, it brings no meaningful facts to the table, only conjecture and opinion, ergo, they do not support your conclusion that these cars aren't safe.
You might be writing history, joining a certain individual who proclaimed: 'The horse is here to stay but the automobile is only a novelty—a fad.'
The fact that an AI doesn't fatigue, doesn't text, doesn't lean over to grab a water bottle and cause a head-on collision, doesn't fall asleep, doesn't drive drunk, doesn't run red lights on purpose, doesn't forget to signal, doesn't speed and has 360 degrees of vision and laser-radar object detection and processing all this information at once where a human has to rely on his eyes and brain and reaction speed, all of which are affected by his physical condition and which deteriorate when he gets older. The AI will sooner or later replace a human driver. If you will, you could consider the current form a very sophisticated version of cruise control, where a human supervisor is still required.
But I could see driverless taxis in Vegas taking you from your hotel to a casino (and back), by just stating your destination, confirming it and paying with your NFC enabled phone.
