I'd do one of the two:
Hero's Route:
-Modify car radio to blast input as loud as possible in every possible direction.
-Get a few extra tanks of gas to fill the backseat
-Modify gas tank to automatically draw from extra tanks as well
-Get a road map
-Drive along blasting music all over the city until all the zombies are following you
-Drive backwards and run over all of them.
Survivor's Route:
-Get a Van
-Pack it full of food, water, several MP7A1s, and ammunition
-Grab a Bible, a Zombie survival guide, and a Military survival guide
-Get several car batteries and wire to create a DC-AC power adapter (to recharge stuff)
-Get my laptop
-Get iPhone
-Find friends that are still alive
-Drive into the sunset, slaying zombies through the windows of this Van.
