I felt bad at first not seeing the guy in the car. On the other hand, two other people *also* looked in (one with a flashlight) and didn't see him either. It even took a minute to figure out what the cop was pointing to when the cop saw him.

Given the speed he must have been going, and the lack of seatbelt, I seriously doubt he survived the impact. It's a little sobering to think he was there for 45 minutes with no one noticing, but there really wasn't anything that could have been done differently even had known.
