Consider how long it took PCs to reach the same stage (with a fraction of the adoption). It was like 20 years from Kenbak-1 to the 90s PC era.
I think people are not yet ready to accept the exact same thing is about to happen to cars. Some company will have a perfectly usable electric self-driving vehicle and will produce tens of millions of them a year. They will be an appliance, like your toaster, and nobody will care anymore.
I'm sure it will happen to other things in our lives too.
I do believe the future you outline will happen but IMO the timeline is very far from clear. Significant challenges remain for self driving cars.
