Everyone who don't own a car have significantly less access to roads than someone who do.

Of course it's possible to compare the advantages and drawbacks of different modes of transport. No society can function without roads, but it's still a question of priorities.

Most weeks I spend more hours cycling on these roads than driving.

Imagine how much less maintenance cost your biking causes than driving a car.

A lot less! So we (society) should be promoting cycling as much as feasible. Also bike parking, which is often forgotten. My town is very bike friendly in nearly every way, except there's no secure bike parking which limits which stores I can bike to.

> Everyone has access to a road. Not everyone has access to rail.

Similar argument can be made about highways to which not everybody has (direct) access, they are not a matter of life and death for most businesses and are heavily subsidized.
