Maybe he wasn't drunk, just shaken from the accident.

However, he was walking in wider and wider circles, looking concerned about his car, until he finally broke and ran. That was intentional. And yes, he was chased down.

Most people would be concerned about their car and formulating a plausible excuse for the police when they inevitably arrived. The only people who run from accidents do so because they have committed another crime they don't want to be caught for (be it murder, DUI, or being here illegally).

And based on where I was, my broad assumptions are rarely far from the mark.
