I've ridden in a Waymo. It was awesome! I've only ridden it a couple of times and for no more than 10 miles each time. If I had been a safety driver, I would have intervened ~5 times: - ~3 (maybe more) when it stupidly turned on its turn signal while stuck in traffic in a middle lane at a light. Changing lanes wouldn't have even been desirable. - Another time when it parked itself for pickup behind a car that was ready to leave. It blocked him for really no reason - Another time, it was seriously confused by a car backing out of a space in a parking spot near its intended dropoff point and just behaved... strangely, with weird unnecessary lurches. None of these were safety related. TBH, measuring interventions is really hard for this reason. I remember hearing anecdotal reports that Waymo had a decent number of non-safety interventions back when they had safety drivers. I wouldn't necessarily suggest being an early adopter of robotaxi with no safety driver either, but I don't think these numbers can be extrapolated to show that with any meaningful confidence. This is especially true given that the initial drives will likely be in geofenced areas.
