It took like 100 years to build the car-hell we have now. It’s going to take a lot of time and effort to fix it.
And people are, famously, stupid. They’ll fight like hell to avoid change, but once it’s in they’ll fight like hell to keep that change.
Plus there’s a lot of selfish idiots that need to be overridden.

How will it reduce demand for parking? Do you envision the car will drop someone off and then drive away until it finds a parking spot that’s farther than the person would want to walk?
That sounds like a very hard problem , and people wouldn’t be happy waiting 5-10 minutes for their car to navigate back to them. Or it would just cruise around looking for parking, causing more traffic.
