These ideas are beyond delusional (in today's world).
> everyone could have access to [vehicles] when desired
Uber is trying to do this, but has a lot of problems, from unpredictable pricing, surge pricing, long wait times, shitty drivers, chatty drivers (?), seats with puke all over them, ... self-driving cars could solve some, but not all of these problems.
> everyone could have a home with desired proximity to others
No, the reason real estate in e.g. NYC is so expensive is that everybody wants to live there! The only way to fix this is to fundamentally decentralize our economy and education systems, but that's a whole lot more complicated than "city layouts".
> [education, medical care and communications infrastructure] would be universally available and effectively free
Maybe education and communications, but with medical care almost certainly not... The main issue is that medicine doesn't save people's lives, it just prolongs them, and that can always be done better... So fundamentally, the demand for medicine is unlimited, whereas the supply (doctors) is limited, so whatever system of "free and universally available" system you design, there's going to be tradeoffs. Tradeoffs like, "do I fix my teeth or my eyes" and someone is going to have to make that choice. Personally, I'd prefer that to be me (with my money) rather than my government.
It is true, perfection shall remain elusive. You can't please all of the people all of the time. That said, more equitable systems with far higher qualities in terms of environmental impact, resource consumption and sustainability, as well as fundamental service availability are clearly within reach.
You raise a particularly good point about the overall properties of systems for mass medical care, but people don't live forever. Cancer is one answer. Solutions that reduce or delay post-facto treatment with holistic and pre-emptive approaches (better regulation, better education, better diets/life choices) may be another.
