Rust reduces overall weight.
 

I am trying to look at things in a more... positive light. I mean a rusted out engine shelf with a few holes has got to weigh less than a nice crisp all metal one. Maybe I want to see parts of my muffler when I open my trunk. Metal conducts heat! My battery tray has less metalic mass than when new, therefore less heat is retained in my engine compartment, thus a cooler running engine. Now that I have a lighter car and it runs cooler, does that mean I go faster?

Additional holes increase airflow, drying moisture and preventing further rust. Until it rains...

Excellent point.

So is your car Yellow? They say yellow rusty cars are faster.

You should put your car through a hail storm if you want it to go faster. All the little divits help with aerodynamics.

Why do you think golf balls have them? Cause the ball goes faster and farther with them.

Idk, something I told my uncle when he was beating him self up when he drove his 2002 Subaru WRX in a hail storm on the way back to Chicago from Ohio for some race event.

$800 bucks of hood damage he got that day, still hasn't fixed it.
