Cars take up unnecessary space when they are moving too!
In a cruel reflection of the class hierarchies we've created for society we prioritise space in our roads for the single most inefficient users. Effectively devoting a limited resource (#transit capacity) in who uses it in the most wasteful way possible, a privilege of owning a car. We struggle with city councils to get scraps of sometimes temporary space for buses or bikes.
And yet this space is not enough. It will never be enough.
