That makes sense. Looking at it again I did see some cars along those ways in satellite imagery, but footways are primarily designated for pedestrian traffic and not vehicle traffic.

You could reclassify these footways to "highway=pedestrian" since this classification allows some vehicle traffic, but is still primarily for pedestrian traffic. 

Here's a link from the wiki to support it: https://wiki.openstreetmap.org/wiki/Tag:highway%3Dpedestrian#:~:text=A%20highway%3D,primarily%20by%20foot

Let me know if you have any other questions!
