When you go to a hub, warehouse, or compound with people and cars blocking your way, get a truck and run into the cars and people until it catches on fire. Then, finish off the other people that are still alive.

When you go to a hub, warehouse, or compound with people and cars blocking your way, stand close enough that you can lock-on to a person. Take either dynamite or a Molotov Cocktail and throw it. It will blow up the cars next to the people. Continue doing this until you have reached the hub, warehouse, or compound.
