Our perception is, I would have thought, quite reliable. It's not unfaulty, and there are sometimes certainly some variances between people's accounts of actual events, but reliable, I think they are.
I'm not really sure what you mean when you say perception is unreal. If I didn't know better, I'd say it comes across as an exclamatory remark, almost as if you are in awe, but I'm pretty sure you don't mean that, so what do you mean? That perception is not real? Why would you think such a thing? Rhetorically, can't you perceive the road when you're driving? Perception is a real phenomenon, even if it's not a thing per se.
When you say that concepts are not things, that brings to mind a very important point. You're right. It's not a thing (in the narrow sense of the word, "thing") (i.e. it's not some thing like a chair or a tree that you can touch). But, it's something. It's not some thing per se, but it is something. In fact, "some thing" implies "something", but "something" doesn't imply "some thing."
If our perceptions were at all accurate the first scientific instrament would never have been built...
With out the form of the road in your mind, as a concept, you would not even recognize it as such...But then, you would probably not be driving which involves a lot of other concepts...See the World as Idea, by Schopenhaur...
Res from Latin, our source of the word reality means thing...Something of substance is a thing, but seeing something completely new, we cannot classify it, but the second time we see it we can recognize it, and begin to classify it... Concepts are abstractions, the facts of the matter at hand, by which we recognize our reality and begin to recreate it in a form more to our liking...
