The rental car insurance will cover a chunk of the car he destroyed, but they will still go after him for a good amount. The DUI plus accident usually is auto jail time even with a good lawyer (can be as low as a few days), but it could be 30 days to more if they want to throw the book at him.

With all the 'little' things you listed it adds up to a bunch of big items that a court will find hard to pass over. Also depends on his past record, is this a 1st time incident or has he had past troubles.
