They’re naturally opposed in a way. Bike infrastructure is car infrastructure, you need protected cycle paths etc where there’s a lot of cars or they’re going fast. If it wasn’t for cars, the current infrastructure is great for bikes.
I can recommend Carlton Reid's "Roads Were Not Built For Cars" book as a history of the early development of modern roads (i.e. tarmac). Many of them were funded by cycling societies before cars became commonplace. Also quite a bit of interesting history of the early cars.
