@balsoft @farbel with properly phased lights, level crossings don't slow down car traffic; what slows it down is too many cars being used, as they are very spatially inefficient. Congestion pricing in London, New York and other cities has increased traffic speeds by replacing car usage with transit, walking and cycling.
@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.
@farbel @balsoft I do indeed. I recommend a good rain cape - I have one of these https://cleverhood.com/products/urbanaut-cape and it works great. I may need to get some waterproof trousers for very heavy rain. Snow and ice is harder, yes, but it's not persistent enough where I live to need to switch to studded tyres.
