My neighborhood has roundabouts. A couple of times when there's not any traffic around, I've let autopilot attempt to navigate them. It works, mostly, but it's quite unnerving. AP wants to go through them ready faster than I would drive through them myself.

I think you and the author are drawing conclusions that aren't supported by the quote.

The engineers stated it's "nowhere close" to being a finished product which is evident by the fact that it's only L2 and in beta.

The DOJ is investigating but we know some of these crashes where from people disregarding the safety features (like keeping your hands on the wheel and eyes on the road) when they crashed, so what comes of the investigation is still up in the air and I think a lot of the motivation is driven by publicity from articles such as this and not necessarily because the system is unsafe to use at all.

The truth is that nobody has achieved full automation so we don't know what a full automation suite should look like in terms of hardware and software. The Mercedes system is a joke in that it can only be used on the highway below 40MPH. I dunno what speed limits are where you're located but in my area all the highways are 55+MPH.

Furthermore, the robotaxis are being used in places like Vegas where they're geofenced to premapped city streets in areas where the weather is perfect all year round. The entire industry has a long way to go before anyone reaches a finished product.
