Yes TA, I know my area well. Point being, you can not "always" see them with the naked eye. Even "IF" their not on the move. "Most times" you can make out a still or motionless speck, at long range....sure. More than likely a fox or a coyote. BUT, when their hunkered down in a dip or a drift, hidden in slough grass or along a grassy creek...whatever. You will play heck seeing one, even if your driving slow.
Sometimes, you can only see a piece of them. Or not at all even useing binocs or a spotter. As they are out of your line of site.
Believe it or not, I get to know the local coyotes by identifying them. From their size, coloration & where they hunt/bed. Not to mention, their territory. Although they are sometimes regularly irregular as in their day to day habits/patterns. Over time, I have them figured out pretty well.
Most coyotes I hunt on a yearly basis, from one yr to the next. Are mainly the locals. Specifically the alpha pr.
Another reason I drive "slow". Is when I pass a valley, I look back over my shoulder[both sides of the road]. To view hidden terrain. I would otherwise miss, if I "only looked 180 degrees", driving fast.
But I don't just look 180. I look 360.
