It's great that you point out the differences in perception between your own ears and the recorder. The recorder has a much more limited distance that it can pick up accurate sounds, while within that distance it is much sharper than our own ears. Our ears have a much farther range, but some sounds seem muffled. I wonder if those farther away sounds are there, but are so faint that they would only be able to be heard if the car noises or other overpowering noises were lowered. It would be interesting to find out how powerful these recorders are.
Even though the recorder can pick up extremely detailed sounds up close, it picks up too much detail as well. As a result it is harder to pinpoint exact sounds like you mentioned footsteps etc with the excess of background noise and vibrations. I think this is an interesting to note comparing the human perception which narrows down and specific sounds for you and block out others, and the recorder.
