Well, I think that 95% of the photos that we all take are just place-fillers, and pre-ordained presses of the shutter button. We are ultimately responsible for our shots, yes, and sometimes we simply must make photos, no matter how well they might or might not turn out. Ah, yes, the CAR window is where the water droplets came from...makes perfect sense...I appreciate you telling us more about the photo, and about your thought processes. Pretty good technique for 25 MPH...no obvious motion blurring....you must have had decent shutter speed.
THis might be a good time to make a comment: I actually have a somewhat different outlook on "drive-bys" or "Car photos", whatever people want to call them. In many respects, my standards of judging them are different than they are for other types of photos. For example, in studio still life shot by artificial light: my standards for what is good and what is not are very,very strict. But, for spot news, my standards have about 10% of their weighting allocated to the technical end of things.
