I did answer. Quite possibly you won't have control. Your entire complaint is a "you can't precisely manage memory in a garbage collected language? Then nobody will use them." style complaint. And that's demonstrated wrong by history over and over - take people's choice away and do it for them, people like it.

Self-driving car, is the hard bit. "Who will design the smartphone app which lets me tap "go to the nearest mcdonalds drive thru"?" is the easy bit. Almost anyone on any $5/hour microconsulting web developer site could do that bit.

"Oh but who would buy an iPhone if it can't let me control the filesystem? You can't answer, nobody can tell me, it's impossible, the tech can't exist, everybody is stupid" - nope, it sold by the hundreds of millions.

Where will it stop? It will stop wherever there is a space. Maybe you can mash your finger on your app for "closest space right now" or maybe you'll get bored of doing that because it already does "closest available space to the chosen destination" because that makes sense.

"One disabled person will get wet in the rain so the tech can't exist" - most tech ignores disabled people completely, and sells in large numbers.

"I can't voice control tell it to go through a drive through so nobody will use it" - if it matters that much to people in general, mctakeout will partner with car company, let you drive up in your fancy car, and they will walk the food out to you. I'm more worried that the cars will come with a "take me to the nearest McDonalds" physical dashboard button, than that no cars have any way to instruct them to go anywhere off-route ever.

"your $70,000 self driving car" - I don't think most self-driving cars will be owned by individuals, but what does price have to do with it? People buy supercars which can't drive through narrow, bumpy, steep, city areas, there is a market for them. Why do you think there will be only a single self-driving car design which has a binary appeal to everybody or nobody, and therefore must be a single answer to how you will control it, and that there's no room for iteration so it must be conclusively decided and locked in several years before any such car even exists or its capabilities are understood and settled?

"So seriously, how will I command this self-driving car?" - so, seriously, driving two tons of machine around a busy unpredictable space is something you're fine with, but having some buttons is what you think the impossibly dealbreaker is? Touchscreens are an appalling human interface, and having almost every control in a touchscreen hasn't stopped Tesla customers.

"Nobody seems to be able to answer this or even thought about it in any amount of detail at all. Probably because we are so far away from an actual self driving car that a realistic answer doesn't really matter at all." - Yes, good point. Nobody has settled on the trivia, because the trivia is not a dealbreaker compared to whether the car can exist at all. It's like you're obsessing over what font the Dragon space capsule will use on its readout displays, and saying that human spaceflight is all hype because "nobody has thought about it in detail".

But no, surely everyone involved is just stupid for not prioritising shovelling burgers into your face over getting you from A to B without killing you or anyone around you.

"Every time you ask about a specific detail it gets hand waved away as not important" - you asked about details, I gave plausible answers (you won't have the level of control you demand) - you completely ignored my answers because you don't want that (you can't answer! ya boo sucks you can't answer!) and then whine that nobody will give you answers.

"You add up all these edge cases that "don't matter" and you've excluded almost your entire market." - I am still boggled that you are putting "can drive through a drive thru" as if that was a thing people actually do enough to influence their choice of car purchase. Can commute to work? Is affordable? Is safe? Is reliable? Has reasonable maintenance and insurance costs? Is big enough for all the people? Can carry enough luggage? Looks OK? All way more important after the dominating "can actually self drive".
