YOU DECIDE TO ESCAPE ON FOOT
It's likely under the circumstances that a traffic jam will end up stopping you in short order, and just in case there is no explosion, you don't want to abandon your car in the middle of town.
You run down your block and to the next intersection, on either side there are groups of people running in the same direction.
The sound of yelling and tires screeching echoes down the city blocks. You make it about 4 blocks, and realize you haven't had anything to eat or drink in hours.
Up ahead of you is a small convenience store. You can see through the glass that the store's staff are gone, and the store is empty.
Still running you look at your watch, and see that there are 25 minutes left.
