1) The truck doesn't need concealing, you can drive it to the killing grounds and have cops smile and wave at you. Up until the point you start using it as a weapon.
2) What does that matter when on a suicide mission? Who says it's a suicide mission? Even if it is, hitting targets from further away is still advantageous. A .22LR can shoot though a car/truck door, you don't want to be close to a cop.
3) Cost doesn't matter when you know you are going to die or go to prison for life. It affects your ability to procure one. You can buy illegal guns from guys on the street, not as easy to buy a stolen vehicle and keep it concealed so cops don't bust you. Also, more expensive. You can grab an illegal gun for a couple hundred bucks..... not as easy to find a car that works for $200.
4) So what? Anyone can go buy (or steal) a truck and plow, today, with no back ground check. You think it's that easy to steal a truck and plow combo? LOL Where are all these plow trucks that are just left unlocked, in unlit areas that are begging to be stolen? lol
5) You don't think a truck and plow hitting you from behind at 50 mph will surprise you? I think you can hear it coming, and unless you're the first victim it's not a surprise. A building pretty much limits the usefulness of a truck too.
6) A truck hitting you at 50 mph with a plow raised 3 feet off the ground won't? Yeah, probably. Why do you suppose no one uses a plow to kill? Why do you supose the most commonly used weapon is a handgun? Why do you think that is? You're obviously suggesting that using a snow plow and truck is just as good (lol), why are all these poor misinformed people using guns instead?
7) Not as difficult as someone who just got ripped in half and run over with 35" mudders. Again, why are all these people using guns instead of buying a giant truck, equipping it with expensive, off-road tires, and killing people while they're out walking around? It's so much more efficient than having the ability point and shoot at them...

Truck with plow, FTW.
