You don’t think a car can be a lethal weapon?
Sure, it can. However just the fact of a car being in motion is used as the excuse to open fire. It’s like the dog-shooting fad of a couple of years ago. A lot of it is police training that makes deadly force very near to being the first option to be considered or another syndrome that was nipped after only a couple of incidents, of training for SWATs to kill everything that moves when they enter a house “for their own safety.”
