There appears to be plenty of riding space outside the fog lane. I don’t know if Nevada has a legal minimum legal speed limit but some states do. I prefer they not ride on public highways.
Such laws generally only apply to motor vehicles. The Nevada DMV says this (bolding is mine):
"Bicyclists have the same rights and the same responsibilities as other drivers in Nevada. Cyclists must ride to the right unless they are preparing to turn left or are able to match the speed of traffic. Cyclists must obey all traffic signs and signals and use hand signals for turns and stops."
