I recorded a walk to the monument / survey markers using my phone, so their locations could be a bit off. However, I would think that they would better line up to the Open Street Map county boarders. I almost think that what I have recorded might be closer to the truth, as my north-south trail lines up perfectly with the fence row in the areal photo. I do not get out that way very often, these days. Could someone else please check my findings?

Multiple buildings.

There seems to now be 4 lanes at this intersection tagged as having two.

Interestingly, this may be confusing autonomous cars. See the Twitter conversation.

And evidences that Tesla may be indirectly using OpenStreetMap data.

It was recently noted that the sidewalks near MSU are highlighted in blue as cycleways by the Open Cycle Map renderer, however, there is an ordinance in East Lansing prohibiting bicycles on sidewalks (selectively​ enforced). I am recommending that the sidewalks be retaged in the following way:

highway=footway
footway=sidewalk
(or where appropriate)
footway=crossing

I don't have time to do this right now, otherwise, I would do it.
