ndrw6, but people are pointing out how this makes the data harder to work with.
It would help if amalash would reply and acknowledge the incorrect mapping and explain the use case they think they are serving, but since this changeset comment they've ignored they've gone on to:
Map sidewalks to nowhere (which can't even be seen in the aerial imagery) in Saskatoon, Canada:

Regina, Canada:

Toronto:

North Battleford, Canada:

I suppose at least in Canada it might be a less confident assumption that there will be a sidewalk, but mapping a sidewalk to nowhere doesn't feel of much use to anyone.
