"This is my first time ever playing BNG." That's how Eon opens his BeamNG session, and right away you can tell this isn't a normal driving game. The very first thing he points out is that "this game has the most similar crashes" — meaning the crashes look the most like real life. He and his dad have watched tons of monster-truck-jam videos, and now they want to do the same thing for real inside the game. The plan isn't to win a race. The plan is: "I want to do some experimentation."

Crashes that bend like real metal

In most racing games, a crash just plays a pre-made dent — the same animation every time. BeamNG is different. It uses soft-body physics: every car is built from thousands of connected points, like a metal skeleton, and the computer calculates how each point pushes and pulls when something hits it. So the car bends, crumples, and breaks the way a real one would.

Eon sees this the hard way. He drives toward a bridge way too fast, crashes, and the game tells him exactly what broke: "rear drive shaft broken, front drive shaft broken, engine is stopped." He's amazed: "You can actually see what's going on here." That's the difference between a cartoon crash and a simulation — the game isn't pretending the car is damaged, it's tracking the real parts that snapped.

Why a simulation makes your computer lag

Here's the surprise lesson of the whole video: the game keeps freezing and lagging, and Eon figures out why. "There must be — that's a really, really hard to simulate all this," he says. "It's a simulation that requires a lot of computational power."

This is a real computer-science idea. Drawing a fake dent is cheap. But calculating how thousands of metal points bend, every single frame, is enormous math — and his computer can only do so much of it per second. When the math piles up faster than the computer can finish it, the picture stutters. Eon nails the takeaway: "My computer can't handle it... I think we need to upgrade our computer in order to handle this heavily simulation." Lag isn't always a bug. Sometimes it's the honest cost of doing real physics.

Turning gravity into a slider

Because BeamNG is a sandbox, Eon discovers you can change the environment — not just the car. After hunting through the menus (Map → Mod → Vehicle → Environment), he finds a gravity setting, and this becomes the best experiment of the video.

He reads the numbers out loud and reasons through them like a scientist:

  • Earth is about -9.81 — that minus sign means it pulls you down.
  • The Moon has less gravity, so a car barely falls.
  • The Sun is set to a giant -274, and he predicts correctly: "the gravity of the Sun is extremely strong — it will drag us down." When he flips it on, the car plummets so fast they shout "the wind!"
  • Negative Earth gravity does the opposite — it launches the car upward. "You like fly all the way to the sky... it might go to space," he says, watching it shoot up like a plane.

Then he pushes too far. With the Sun's crushing gravity, the monster truck slams down so hard that the game can't keep up — "I think we broke the game... the car no longer exists," and it restarts itself. Breaking the simulation taught him where the limits are, which is a perfectly good result for an experiment.

Experimenting your way through the unknown

Eon says "I have no idea how to play this game" more than once — and that's the point, not a problem. He adds a dummy mod (he explains it clearly: "mod is short for modification, M-O-D... there's a main game and there's a modification"). He tries a Supra, a giant bus with a cape, a moon car, an off-road trail with markers. Each time he picks a vehicle, drives it, crashes it, repairs it with the repair tool, and tries again. "We're testing it... we're doing the experiment, we're doing the simulation." Not knowing the answer and trying things to find out is the experiment.

Try it

You don't need BeamNG to think like Eon. Drop a small ball and a big ball at the same time and watch how they fall — that's gravity, the same force the game turns into a number. Then in any driving game you play, watch a crash closely and ask: did the car bend differently this time, or did it play the exact same dent? If it's always identical, it's a canned animation. If it changes every time, you're looking at a physics simulation — and now you know why that kind of game makes a computer work so hard.
