more zombies

Somehow, in the last few minutes, zombies have appeared out of nowhere. They seem to be coming at you from all directions. You look around for your friends and see a scene of mass chaos. Several of your buddies have fled while others are trying to fend off their own share of zombies. You also see that Steve has now become a zombie and is attacking your mutual friend Sara. You briefly think about helping Sara but then remember how annoying she can be and let karma do its thing in the form of Steve. You run from the bonfire onto a street and almost get hit by a car. The car slams on the brakes just in time, sparing your life. What do you do?
