I live in the dutch city of Eindhoven and it's both convenient to have a car and convenient to ride a bicycle. This is possible as long as you invest as much in bicycle infrastructure as you do in car infrastructure. When a road becomes too wide to cross by bicycle the city here either builds a wide bicycle tunnel or a suspended bicycle roundabout. Those types of infrastructure are expensive, but it's the kind of thing you get if you don't put all of the city's infrastructure budget into one mode of transportation. What does a suspended bicycle roundabout look like?

Just build a bicycle bridge over it: https://goo.gl/maps/WqLgJdhsTsr5sufE9 https://goo.gl/maps/WqLgJdhsTsr5sufE9 Of course you do need to make sure that there are actually places worthwhile going to within a convenient cycling distance. Which involves building lots of multi-family housing at the edges of downtown. With shops located within those neighborhoods. Rather than huge suburbs with exclusively single-family homes requiring a car to even do grocery shopping.
