@balsoft @farbel I think your imaginary city describes how the citibikes and ebikes work in NYC now - you pick one up and ride to your destination, then dock it again. This augments the transit and coexist well with pedestrians.

In terms of street level crossings and coexistence, you want to switch to the european model where cycleways and sidewalks are continuous and have priority, and cars yield to them, using roundabouts more when an intersection is necessary.
