Depends on how the sidewalk ends at the intersections and if it dumps you onto the road at some awkward spot. Many of paths are nice until you reach another road.

Also, those concrete slabs don't look to be the most even.

Also, while there appears to be no pedestrians, what if you did run into one? That sidewalk isn't very wide. It would be difficult to pass the pedestrian if you came up on them in the fog at speed..

So yes, there are reasons to not ride that sidewalk.
