While he CAN be sentenced up to 9 years, it doesn't mean he'll serve 9 years.  Most likely, the judge will sentence him to 5 or 6 years with half or more suspended, + the 180 days in jail for the DUI.  Then he gets to count every day he spent in jail pre trial toward his sentence, plus he'll get 1 day shaved off for every 2 days of good behavior when he's finally remanded.  Let's say the judge gives him 6 years with 4 suspended, and he spent a total of 4 months (120 days) in jail before sentencing.  That pretrial time effectively counts toward all 180 days of his DUI sentence, with good behavior. He'll go to prison for 2 years, but be back out on the street in 16 months, again with the good behavior caveat.  So no, I don't agree that justice would be served for running over a woman and leaving her in the street to die.
