11% seems incredibly unlikely. How is a single car going to get 10ppl (on average!) to work during rush hour. Add in destroying transit, and the kind of sprawl that "Futurama" fantasies tend to come with, and I doubt this is going to work. Many roads are already fully congested during rush, where could a 10x capacity increase possibly come from... The last studies I heard about talked about reducing the required vehicle Fleet by 3 vor 4, while actually _increasing_ VMT.

> where could a 10x capacity increase possibly come from Eliminating street-side parking single-handedly gives you 2x to 3x on side streets. Tighter packing and better routing does a lot of the rest. You can't do the latter until a zone goes 100% autonomous, which is unrealistic for e.g. Dallas but very much so for downtown Manhattan. > Add in destroying transit Nobody said anything about destroying transit. Earlier, I explicitly mentioned rail for within-density transit.

  It you turn parking lanes into driving lanes, you're not increasing the capacity of the existing infrastructure, but creating much more driving infrastructure. It also won't 'return' parking to the economy. Consider the 'staying quality' of a <parking lane+driving lane+parking lane> residential street turned into a 3-lane thoroughfare. That's exactly the sort of dystopia that new urbanists and sustainable mobility advocates are warning about.
