NM has sort of a lot of wide open country there, so maybe being a pedestrian in NM isn’t that practical. B/c there are so few of them, the pedestrians don’t know how to behave safely, add to that the drivers aren’t used to seeing pedestrians much. You’d think there would be quite a few bicyclists tho, NM seems a friendly bicycling place. But maybe that’s only in the resort areas like Taos. Other places, drivers aren’t expecting to see bicyclists.
I know from my own experience that being a pedestrian or a bicyclist in Colorado 30 years ago was considerably less safe than where I live in Calif now, for those reasons. The drivers there just weren’t expecting to see me in either of those roles on the highway. Some of the older drivers were actually hostile to a pedestrian or a bicyclist even being near the roadway and bothering them. Probably less so now of course.
