I'm too late to contribute to the discussion, but there are serious obstacles to full implementation of electric powered autonomous driving vehicles. For starters: Impacts on the oil and gas industry and all other sectors of the economy related to it, the cost of implementation would be staggering and expensive to maintain, insurance will still be required because these systems will fail at some time and someone will have to be responsible, cultural change is slow meaning people will be hesitant to give up their car and the driving experience, weather affects the ability of autonomous vehicles to stay on course, loss of gas tax revenues to the federal and state governments who build and maintain the roads system, likely increase in traffic congestion due to empty AVs driving around; and finally battery technology still limits the operational range of these vehicles.
MnDOT is researching this as are a few other states. Here's a link:

Welcome to the discussion. It's not too late at all. I'll go point by point because I'm in the middle of a migraine and my short term memory is total crap at the moment.
Firstly, it's happening. The only question is how it happens. Gas powered cars will go away. The only question is how soon.
Secondly, fully autonomous driving systems are happening. We'll first see them in trucking. There's already a module that retrofits existing rigs for $50k (est) that's in deep beta right now. Mercedes, Volvo, Kenilworth, Peterbuilt, Walmart (in conjunction with Peterbuilt) and Tesla are far enough along that they're taking orders for trucks that are semi-autonomous and are very close to making them fully autonomous. Walmart has order 15 Tesla trucks in addition to what they're developing with Peterbuilt and none of the vendors will be able to keep up with orders for some time.
Thirdly, fleet insurance is already a thing so that's not a problem. And EVERYONE from Hertz to to Uber to Ford are trying to figure out the alchemy for a subscription based model. The problem will be people who do things like in person sales or actually need to move around for a living because personal insurance will go up prior to the wide adoption of these leasing agreements because underwriters and risk assessors will realize how bad people are at driving compared to computers. So, yeah, there's gonna be some really wicked growing pains with this and as usual, the worst hit will be those on the lower end of the working class.
Fourthly, it's not just the lack of a gas tax for maintaining roads, but it's also the lack of traffic violations that fund cities. Los Angeles gets fully 33% of its revenues from traffic violations, from parking to traffic tickets. And most of their payroll actually comes from traffic revenues as it's easier to manage that liquid money that budget from property tax assessments, etc. What are big cities that rely on traffic infractions going to do when there are literally zero funds from traffic fines/parking tickets? That's a question that cities need to answer NOW because it takes a lot of time to reorient large city and/or state governments with different revenue streams.
Fifthly, there's almost certainly going to be less traffic congestion seeing as how I mentioned that there is almost certainly going to be a SuperShuttle model where people carpool to work, but you don't have to worry about Gary being late or Linda's car being too small, etc. There almost certainly won't be accidents on the road, so that means fewer cars on any stretch at a particular time and if there is a "road manager" type of road traffic control that routes you, you'll be put on an optimal route both for yourself and all the other drivers (as opposed to now where you simply make decisions for yourself based on traffic conditions in the moment). Empty AVs will likely be driven to lots and then driven to the closest staging lot during off-peak times so that they can be delivered in a timely fashion to the next rider.
Lastly, battery tech is on the verge of major improvements. Tesla just announced its new Roadster with a battery with over 600miles. Granted, that's for a lightweight car, but it's still got all the amenities including A/C, leather seats and all those electronics. And that innovation which is mostly an iterative improvement isn't even the next breakthrough that's coming.
I fully expect that there will be a proof of concept for a battery that can take a car from SF to NY on one charge in the next 10-15 years.
The unknowns in all this are things like a) who the winners will be among all the vendors? Will there be an Apple-esque winner that takes more than half the market? Will there be vendor diversity like we currently see in the auto landscape? b) what pace will the market switch and will the changes align close enough that people aren't seriously harmed? I mean if the insurance market really gets ahead of the auto market, that will really negatively impact some folks... c) what are cities, states and the Federal gov'ts going to do with the ever decreasing gas taxes, personal auto registrations, parking and traffic revenues, etc? d) what are all the displaced workers going to do? What with all the online shopping, now's about the best time ever to be a truck driver (not the traffic, cuz that's always sucked or the weather, cuz...yeah) but that profession is about to go the way of the travel agent. Truck/car mechanic? That, too, especially if they go the fleet method which makes the most economic sense for reasons that would make this a multipage post if I were to list them. Autobody repair? Few and far between because....a ton fewer crashes. So how does the economy deal with this change?
The economy will have tremendous opportunities for everyone if we eschew monopolies and foster entrepreneurship and innovation in the market. That will also help us truly address the job losses.
As an aside, if we would foster a national build out of fiber as in investment like the National Highway System, people wouldn't have to congregate in big cities nearly as much and smaller towns would have the population to scale and offer more jobs/services/business options that typically elude smaller towns today.
I fear we will just treat people as consumers and we'll see these big companies as gladiators and celebrate the last one standing as if that's what makes for a good economy. Jeff Bezos as a Trillionaire isn't great for the economy as a whole. Better to have a million millionaires...if one were given the choice, I mean.
