There are a lot of folks who go out and buy a high quality HD camera and think they are qualified to create a shooting school. Typically speaking, the more complicated and obscure the instructions, the crappier the school. A fella named Dallas Lloyd has created the worst way to return fire from a vehicle. Just watch it...
WTF!? When would you ever use this technique? If you were taking fire from the front or the side of the vehicle why would you do any of this? As a quick tip, the safest places in your car from oncoming fire are behind the engine block, behind the gas tank (they don't explode when you shoot them despite what Hollywood has shown you for years), and behind the tires. The main reason for all of those spotss is because they are likely to slow or stop the bullet from getting to you.
Why the hell would you get out of your car and then hang upside down to return fire is beyond me. Also the door of your truck won't stop bullets worth a damn. Shooting upside down single handed isn't typically a recipe for accurate fire. God help you if you have to reload from that position, and don't even think about doing this this with a rifle.
I don't think this video is a parody. I think this guy is actually attemptintg to teach people something that might get them killed, injured, or cause them to drop their pistol on the ground and then jump out of the truck. Please don't attempt to recreate this situation.
