"Fancy cruise control" as you call it is already a product, is already in shipping cars, and you can buy it today. It's not five years away. Some currently available mass production cars already have the ability to maintain their lane, change lanes when directed, and maintain speed and distance in traffic. It's not just research and development, it's for sale.
What's going to be here in five years is a product that will take you from point A to point B without you doing anything but telling it where you want to be. Those points will likely not initially be any point in the country, but they will likely be any point within a city that's accessible by city street. Successful research and development leads to products, and by every reasonable measure, the current research and development is very successful, since they're already putting those research and development cars on the public streets.
And since you mention freeways, driving on the freeway is actually the easy part. City streets are a much harder problem, but they're a problem that's also nearly solved.
Please explain why you think I don't know what I'm talking about. Do you think the technology demonstrations have all been faked? Do you have some sort of insider knowledge about it not working that contradicts all the information that's been published about how well these systems work now?
You're declaring it "hype" when anybody paying attention can see it's happening. So please, if you've got something useful to add, do so.
