Manhattan, famous for its congestion-free streets :-)
Calling cars "decentralized" is funny, and more than a little ridiculous: American car culture is a result of centralized planning, both of highways and cities. It'd be more accurate to call them "individualized," with the misaligned incentives and commons failures that that implies.
Your argument is anti-scientific in a way. We see in nature that decentralized systems are more robust yet you are arguing the opposite.
Decentralization is not a virtue (or end) in itself when it comes to public infrastructure. Robustness is also not intrinsically tied to it, and there are a variety of senses in which the American road network is not particularly robust: congestion and unsustainable funding schemes are just the first two that come to mind.
Who cares about being interesting, I can go around outages in the network with a car where trains can't.
You should be arguing for smaller cars not less of them.
You, ostensibly[1]!

I'd be more than happy to take both :-)
