Well its not about individual ownership its about businesses testing commercial self driving cars right?
Seems to me that a company is going to need to sink many millions in to design, build, and test a truly road safe self driving car no? Even considering it as a hardware and software mod to an existing model.
Individual ownership of driverless cars is out of reach, and always has been. This pilot program brings it a step closer, despite clearly just a test (e.g. requires two drivers in the car)
