Porsche used to fill the chassis tubes on the 917 racer with N2 and had a gauge on the dash. If the gauge dropped pressure. The chassis had a crack and would fail in short time. Causing an accident. So it gave the drivers a chance to slow down.

That. Is. Amazing. And absolutely genius.

Happy holidays!

Back in the 70's. Some Nascar crews chiefs used to stuff extra fuel line in the chassis. Sometimes being able to add another 3~4 gallons of fuel. This would give them another lap or two before pitting.
