There’s tons of roads like this in New Mexico. The only saving grace is low population density. I’ve driven 100 miles without seeing another car, it’s always a bit of a pucker factor when someone is coming the other direction given our DWI statistics.
I spent the night in Winnemucca, NV and left the motel about 9 am. At first, the road was pretty empty, but it was filling up by the time I got to the OR-NV border and even more busy the further I went.
