Shooting a car's gas tank causes the car to blow up.

Was it not NBC (or some other alphabet network, not that it matters) that got caught having a gas tank explode before the  "crash" car ever touched it?

Hey, the leftist media/Hollyweird had been peddling bullshit to the morons for decades and they continue to lap it up as the truth. 

How else to you think Obunga could have sneaked in?

On November 17, 1992, Dateline NBC aired an hour-long investigative report titled "Waiting to Explode," which focused on allegations that General Motors' Rounded-Line Chevrolet C/K-Series pickup trucks exploded upon impact when involved in collisions due to the poor design of the vehicle model's fuel tanks. Dateline '​s footage showed a sample of a low-speed accident in which the fuel tank exploded; the explosion during the crash test would later be discovered to have been rigged by producers with the program, who placed remotely controlled model rocket engines inside the truck's fuel tank to initiate the blast. The program did not disclose the fact that the accident was staged.

GM hired investigators from Failure Analysis Associates (FaAA, now Exponent) to study the footage; FaAA investigators discovered while reviewing the video that smoke had actually started to expel from the fuel tank six frames before the actual impact occurred. Acting on a tip from someone involved with the Dateline crash test, investigators with FaAA searched through 22 junkyards in Indiana before finding the charred wreckage of the GM pickups.[10][11]

It was also later revealed that the Dateline report had been dishonest about the fuel tanks rupturing and the alleged 30 miles per hour (48 km/h) speed at which the collision was conducted. The actual speed was found to be higher than stated, around 40 miles per hour (64 km/h), and after x-ray examination of the fuel tanks from the C/K pickups used in the televised collision, it was found that they had not ruptured and were intact.

Bad guy is shot and gets thrown across the room, backflips and breaks through the glass window.
