And years of regulatory red tape. Moving from current -> self-driving legal and regulatory framework will be one battle. Moving from that to a driverless model will be much larger.

And those updates have to percolate through federal, state, county, and city level regulations. Making it an inherently slow process.

I agree, and I think that's also good for driver and traffic safety. As I mentioned a while back, in case of traffic light going dark, officer has to stepped in to regulate the traffic. Current self-driving car is not capable of handling that without any faults. Among cars, they need to negotiate who to move first on a all-away-stop sign. Self-driving cars need to be able to get data from government relating traffic condition. Currently we all rely on GPS data to determine whether there's congestion or not, as well as user's input (Waze) but that's far from enough to be 100% driverless.

Dataset availability is really really poor today. We can move with great confidence on known conditions, but so many edge cases remain to be solved.
