here is the write up on the gas pedal specifically
A couple unique problems,
-
mechanically dis-assembling the pedals broke the whiskers and fixed the problem
-
Using a standard ohm meter also destroyed the whiskers via melting them from overcurrent without detecting them

Everyone I have worked with from nasa is absolutely top notch as well. A really good example is the Tin Whisker Symposium which diagnosed the failure of the toyota gas pedals in great detail.
They are the foremost experts in a ton of different fields at the same time.

you are right that I am extrapolating off of the water density chart I posted, and even so poorly.
Goes from 1000 to 1080 kg/m³ over 200 Mpa, by the time you get to 1000Mpa it would be 1400 kg/m³ and the nearly equivalent air temperature goes to around 1150 kg/m³
The log plot threw me off. This would be even worse for salt water since it is more dense than pure water which is the chart I have.

Air is much more compressible than water is.
2000bar is 200Mpa, the units are different on those charts, but by 10,000 bar air will be more dense than water at around 20C.
E: I extrapolated poorly, read the response to /u/Origin_of_Mind
looks like these are the wrong charts and below 1Gpa water will always be more dense.
