Desire paths Desire paths can be paths created as a consequence of erosion caused by human or animal foot-fall or traffic. The paths usually represent the shortest or most easily navigated routes between origins and destinations. https://en.wikipedia.org/wiki/Desire_path
That, plus if there are any pedestrians using the path, they should get first dibs. Bicycles can ride on grass just fine, but anyone with a walker, a wheelchair, a stroller, or just wants to keep their shoes clean, should not feel like they have to squeeze or get off the pavement to let a bicyclist pass.
Here, the convenient option for bikes is also the most friendly option. Ornamental grass shouldn't even be a top-10 concern. If the municipality won't build proper infra for all users, then desire paths are all but guaranteed.
