Agree. I hadn't seen the MCU model number before, but a quick google search turns up the
spec sheet. Environmental conditions are called out. (Note that the max 80 deg while using the screen is celcius, which translates to 176 deg fahrenheit ...storage upper limit is higher yet.)

So back to google to find how hot a parked car can get in the summer. Lots of articles, most are in the 110-125 deg (F) range - but the worst case I could find stated is 172F.

So it appears that the screen specs were appropriate for the anticipated environment.

Turns out, there is such a thing (not a surprise). It has to do with reliability of critical components.

But it doesn't mean 'every single thing in a vehicle is supposed to be automotive grade'. Here's a helpful chart (left column requires automotive grade, right column does not):

So, draw your own conclusions. I'm sure we don't all agree on this, but thought maybe we could all operate from the same set of facts instead of speculating.
