could he still be alive if he had adequate amount of water in the vehicle?
he maybe had an off-roading accident and could be laying there with broken legs or something
just waiting for help, maybe no signal for a phone ... but 10 days without food ...

Even assuming minimal water (not hot out, which it's not been in Napa, low mid 70's), no physical exertion and his height/weight, he'd need about 4 cups a day minimum to survive. In 10 days that's 2 and a half gallons. Would he have taken that with him? Was it a day trip? Multi day trip? Minimum Amount Of Water Needed To Survive | Backcountry Survival
