Any chance you have a better picture of that yellow sign by the road? It looks like some kinda reflection exposure in the sky. But I think maybe it's a reflection in the windshield....
I see what you mean about the sink hole, but there are some lighting and reflection issues that might make one think something else is there. It actually appeared as a pretty big pothole. Have they done repairs in that area? Do you guys have those fractal earthquakes in your area? If so...there may be some road damage or has been in the past.
How were you feeling the days you saw the "sink hole", or what was going on? I find that sometimes visions are like dreams and we need to look at the symbolism of what we see...'\_(**)_/' I've only had a few visions that were accurate to a "T", so I have no idea if others have constant accurate visions of what was, is, or will be.
Directly from dream moods:
To see a pothole in your dream represents difficulties and setbacks in achieving your goals. You need to make some changes in how you approach your goals. The dream also indicates that things are not going smoothly for you in some aspect or situation in your waking life.
