I don't think this is true. No auto maker wants to deal with the insurance overhead involved in installing a "marginally flawed driverless system." Can you imagine that meeting? The moment when some insurance executive is told by GM, Ford, Honda, Toyota, Mercedes, BMW, whoever, that their next car will include a full-on autodrive system? The insurance company will raise the manufacturer's insurance through the roof! Imagine the lawsuits after a year of accidents in driverless cars. Everyone would blame their accidents on the automated system. "Not my fault, the car was driving, I wasn't paying attention, can't raise my rates, I'll sue the manufacturer instead." A few go-rounds like that and no one will want the system installed anymore.
