Jimmy really had a headache now; he had thought there were only three to five people, but now there were ten people within his "Heart Eye" range, including the three in Tim's car.
Not all of these people were just carrying handguns. He had already seen three AR15s, presumably the civilian semi-automatic versions since he noticed no signs of automatic fire. Another person was using a shotgun, the model of which was unclear. The others all had handguns, which wasn't a particularly big problem.
Jimmy crouched next to the front of the car, using the hubcap and the engine as his only cover. He dared not crouch anywhere else; the firepower of the AR15s could easily penetrate the car body. This car was just a random second-hand purchase, not an armored vehicle.
