Tactics : Have 4 Meat Turrets (two on the left of the road about 5-8" away; and two on the right of the road) engage a single target. It won't take long to blow it's tires off. Two volleys.
Once the target is immobile, the Meat Turrets run away from the road at full speed. If the passenger dies ... who cares ? It's only a dreg. And the immobile vehicle is an easy target once the rest of the convoy departs.
