One hour driving will be pretty miserable in typical Los Angeles traffic (and note that car commuting costs go beyond fuel – there is car maintenance, parking, and the cost of car itself and car insurance for it if you would otherwise not have the car).
Is there any reliable public transportation that you can use instead if you commute? It looks like the MTA rail lines are next to USC, and they connect to the MetroLink rail lines for longer distance commutes.

Note that an hour driving is effectively wasted. But an hour on the train can be used for reading or sleeping.
