The problem is not the car or the software, it's the environment.
My understanding is that the auto-drive vehicles continuously scan the environment, looking at the road, lines on the road, signs, other vehicles, etc. This works great if everything is marked well and signs exist.
However, if the road is unmarked (fresh pavement), the lines are badly worn, or there are old-n-new lines, things get dicey.
Recently I drove through construction where there were three sets of lines, two looked fresh, and all ended abruptly at different places. *I* had a problem figuring out where my lane was. How is software going to do it?
Self-driving vehicles will continue until someone connected to money gets seriously injured or killed. THEN the house of cards will come crashing down.

These safety problems are addressed in autonomous driving cars.
I am working in the automotive industry, and I can assure you that I would buy an (electrical) AD vehicle from any European or Japanese car manufacturer without any discussion.
I still have my own doubts regarding quality of EVs from China. And do not get me started about the Musk company - nice toy, best car to die in.

Not sure I understand your statement.
For example self driving cars are not going to prevent heated seats from catching on fire. That is one of the recalls.
And Telsa has a recall in effect to reduce the ability of their cars to self drive. So very specific to self driving.

I don't see how any of that leads to OP's claim that self-driving cars will never happen. Recalls happen. All the time. My dad was a mechanic for over 40 years, and recalls have provided plenty of work, even for the silliest things. Buggy self-driving software? That's an over-the-air update, I don't see that as a big deal.
I suppose retro-fitting an existing car with new sensors would be something else. But then, if there was a need for that, the manufacturers would just take the feature away and claim it was never sold as "fully self-driving" anyway.

Just a small note on the self driving car that dragged the person when it attempted to pull off to the side of the road. The person was first hit by a car driven by a human driver. Their body was thrown in front of the self driving car. The self driving car could not stop. (Physics). The human driver ran from the accident and is still being looked for.
Unfortunately, the person fell into a spot that was outside the range of the car sensors. The car proceeded to try and pull over to wait for help with the accident and made things worse by running them over.
Yes, a human being would get out of the car and look to aid the injured person before trying to move their car (unless they panicked and simply drove away.)
Yes, the self driving car needs to have it's software upgraded to include the case where a body is thrown in front of it, collides with said body, and can not locate the body after hitting it. In that case it needs to simply stop, call 911, and wait for human assistance.
Yes, There are many unique things that a car can encounter. Will software ever be up to the challenge? I honestly don't know. But I do know that the current carnage on our highways will continue, with or without automated driving help. Software can be upgraded, people; not so much.

Not sure I agree with that.
Not even sure I agree that that is the best action to take.
As I noted in that was a highway. And at night.
Not sure about you but for me slamming on the brakes at any time on a highway is not something that I consider safe. Not for me and not for the cars behind me.
Also as a driver I have been in an accident where I had no idea what had happened. Also on a highway. So the 'correct' behavior becomes much less clear.

For a driverless vehicle that means programming every possible scenario. That is just not going to happen.
Some examples.
I have been on a higher speed road and the car in front of me hit a bumper that fell off another car and it launched the bumper into my car.
I have seen a car that was side swiped (literally knocked off the road) because it came from behind and speed up in a turn lane besides a long line of stopped cars and one of the cars in the stopped line decided to change lanes abruptly. I saw the car speed up because I was further down the line of cars. Not sure it was even visible to the car that changed lanes.
I have seen a bicyclist going the wrong way down a one way street at night with no lights and moving quickly. I actually know that person and he had previously been in a accident doing the exactly the same thing except that time he was hit and went flying over the car.
Note that in these scenarios it is not only that the car must be programmed to handle it but that the car maker must be able to show that what it did was the correct and best way to handle it.

That however is the point. When those accidents do occur the car maker will be sued for large amounts of money.

I don't think it will - instead, I think the public opinion will shift to revulsion at the whole idea of manually driving a car. Think about existing legislation: seat belts, ABS, speed limiters, the recent whole-of-Wales reduction of the default speed limit to 20mph from 30 - it's all about increasingly small reductions in death and serious injury; self driving offers that a large reduction (which will be touted as a total prevention) may be possible and there isn't a politician who dares fight that! Car companies being sued as a result of their products failing? It happens already and they probably have a budget for it because it's cheaper to be sued than to do the job properly ... 
And as the number of self driving cars increases and the communication between them (to increase safety and economy) rises as well the accident rate will plumet as a result. When humans realise that they can do what they want (legally) while the car does the work they will leap at the chance to browse social media, messages, phone calls, alcohol, drugs, tv, pr0n, ... Stuff they do at the moment anyway while they are supposed to be in control!
I don't commute any more, but my regular commute was an hour each way with the lemmings on a motorcycle and the things I've seen while traffic is moving at 70mph was horrific, phones, texts, newspapers, even one guy with his lappie propped open on the dashboard typing away and steering with his elbows!
Self driving cars will (eventually) be safer: and they are - probably - the future whether we like it or not.

Didn't this famously happen in the '70s with the Pinto, which had a design flaw making it liable to bursting into flames in an accident, but it would have been more costly to retool than to pay out when it caught fire?

I've had almost the same thoughts about autonomous vehicles. There's a whole range of accidents that occur because meat sacks are in control. Have you ever arrived at your destination and realized you have no clear memory of the journey? There's other things our brain does to edit reality. There's a well known example of a group of people asked to watch a football match, and answer questions afterwards. The first question is "Did you notice the guy in the gorilla suit?" Most people miss it. Because your brain edits it out as "not important" to the football game. Similarly with driving - or really any activity.
My thought is that several things are going to happen. Firstly, insurance companies are going to look at the numbers and raise the rates on non-autonomous vehicles, to the point where the average Joe is going to be motivated to move to an AV. Then, as non AV's move into the minority, and communication between AVs becomes standardized, NAVs will be required to have transponders that alert AVs to their presence. Eventually, NAVs will be banned, except in tightly controlled situations (e.g. parades, etc).
I expect that as the technology grows, there will be some terrible incidents. But like the airline industry, investigations and recommendations will continue to make AVs safer over time.

It isn't a matter of whether they can be safer.
It is what will happen every single time that any sort of accident does occur.

Slightly distracting from your main point, maybe, but what I don't understand about self-driving cars is that everybody is doing his own thing.
Why not make this a collaborative effort? So when one unanticipated scenario comes up, someone writes a fix once, the community at large tests it (like bug fixes in open source - in theory) and every manufacturer gets to benefit from it. It seems to me things would evolve a lot more quickly than having everyone roll his own version, no?
Is this a matter of patents? Or each car manufacturer using different types of sensors, so there isn't one common/re-usable source of data that can be acted upon?

There have been attempts of making suppliers and OEMs work together, there are government funded projects but everyone thinks they can do it better than the other, AND the first one coming with an affordable and reliable solution will kill all other. Trust me, I have been working for 20 years in this industry, and the answer to your "why" is that it is run by human beings with emotions.

In the US, such an effort (unless run by the Government) might run up against anti-trust law.

Well, I wasn't suggesting someone should own a monopoly on the technology...rather, it should be a collaborative effort among all car manufacturers. And if that was managed, in turn, by the government, then there's no chance of anyone running afoul of any anti-trust law...

The very thought that in the coming two generations, people are likely be unaware of ...

is somewhat unsettling.

They won't.
But self-driving cars only make sense in a closed system where all of the cars talk to each other and nothing squishable gets on the roadway.
As long as they don't interoperate with each other -- between makes as well -- and as long as there are non-affiliated (human-driven) cars on the road and people and animals can cross the roadway -- the system just can't work.
The current research is fine for ironing out the bugs in preparation for making an eventual future city with a closed road system.
I need to watch Logan's Run again.

A closed system, like a warehouse or construction yard, is not comparable to a city.
Consider what happens if there is an accident in a warehouse.
- Immediate stoppage of most everything.
- Immediate response to the injury
- Any claims of monetary damage, at least in the US, usually are limited to actual provable damages and might even be covered solely by workers compensation.
Additionally, especially in a warehouse, the unexpected is very low. No cows or bears. No high speed chases (cars or foot). No broken water mains.
In a city none of that is true.
