But can a person credibly be charged with failure to render aid if he has the guy's body draped over the dashboard? That'd be a question for the lawyers...
He didn’t do anything to help the guy just in case he was still alive, just kept driving, so yes.
I understand in times of crisis it’s easy to not notice things, but a body in the passenger seat seems highly unlikely.
I took a deer through the W/S into the pass seat and floor(fortunately it died on the way in). Admittedly it was a small car, but the wind coming in through where the W/S used to be was a BIG clue that something had happened.
