Redditor u/QBZ24 titled their post "I was on PTS and the only guy in here had the same idea I did lol" with a video depicting the player and another joining forces to view results of what would happen if gas, fire and cars mixed together.
Here is what happened:
PUBG Players Explode Car Into Air in Public Test Servers
Redditor QBZ24 and another player can be seen playing with fire in PUBG Public Test Servers to see how high vehicles can jump, or in this case, explode into flames.
Although the other player is only seen shooting the gas to create fire or sitting in the vehicle, Redditor QBZ24 can be seen dumping gas from an unlimited amount of Gas Cans provided on the server. With a lot of gas surrounding the first car and the other player inside, the car explodes into thin air, nowhere to be seen.
Second time around, with only a line of gas, the players sent a truck into the air which lands far away and almost looked like it could have hit a plane that just dropped a crate. In the third experiment, the player is inside the vehicle as it is exploded into the air and completes multiple flips and crashes to the floor almost unbroken.
The last experiment was with a UAZ (closed top) and both players are seen flying higher than the previous car whilst spinning to an extent where the game has some frame issues, possibly due to height.
Players can have so much fun on Public Test Servers and with the latest addition of Patch 7.2, PUBG is providing players a chance to show their creativity whilst testing different situations. As for exploding vehicles, it's confirmed that gas, fire and a vehicle don't mix.
