[DeTomaso] Something is so wrong with this

And in the meantime all that 'real time' fabricated data is being constantly uploaded to GM to use against you, saying you 'abused' the car, sorry warranty void!
Alas, I fear that I'm getting old and it is a young person thing; much like texting the person next to you rather than simply talking to them!

Dear Forum,

 
                I was just reading the October Grassroots Motorsports
article about their project car a new Chevy Camaro that they were modifying
and testing on the track.
 
               "...While enjoying the track outing, we confirmed the third
thing that had begun to concern us at Daytona: seemingly very high engine
oil temps.  After just a few laps, the oil temp indicated on the Camaro's
quad gauge pack would creep up to within a couple needle widths of the
320-degree mark.  If nothing else, this warranted some talks with Chevy.

                   We had a chat and exchanged some emails with one of their
powertrain engineers and learned some interesting stuff.  First the oil temp
gauge in the center cluster isn't actually measuring oil temp per se.  The
gauge actually reflects what a computer model simulation estimates the oil
temperature should be based on current information.  It takes data
parameters like ambient temp, rpm, engine load, vehicle speed, gear ,
throttle position and dozens of other data points to build a very accurate
simulation.

                 Amazing, yes.  But the oil is literally 3 feet from you.
It's right there.  Wouldn't it be easier to just measure the temp?  Well,
Chevy says the modeling is highly accurate and quicker to react than an
actual gauge under normal conditions.  And there's the rub.  Under typical
loads the model is exceptional, but when the variables start to greatly
exceed the normal programming thanks to strained track action, even Chevy
admits that it may not be capable of accurately predicting temps."

                 They then discuss the loan of the Chevy old school
thermocouple to install and double check the accuracy of virtual oil pan oil
temp reality with..an actual measurement of the actual temperature in real
time.

                 What is wrong with modern car manufacturers?   A computer
model simulation of the engine oil temperature?  What could ever go wrong
with that?   I am appalled and flabbergasted by such things.  I am a
Luddite.
