There is.

There are villages in the Netherlands where there is no grade separation, bike paths, foot paths or even lane markings.

There are no street signs; the only road rule is to try to keep to the right, where safe and don’t try to occupy the same space as any other road user.

They have no collisions because every road user understands that every other road user has as much right to be there as they do.

When you put artificial rules in place that gives someone else more rights than someone else, that person will feel more entitled. They are less likely to respect other road users.
