Did you hear about NPR forgetting to add an image extension and
then bricking Mazda radios with their broadcast?

If misinterpreted image data was able to alter the firmware, why can't Mazda
reflash it?

The SDRplay program for my RSP1A software defined radio decodes RDS data
when listening (and watching, you can see individual notes) an FM broadcast.

Don't know... Guessing there isn't any money to be made other than
selling you a new car. It's all about money and how to best extract it
from the user/customer...

My guess is that the programmer quit in disgust and no one else knows how it
works.

I've been the stuckee for that thankless task three times. I've solved the
problem; written my own quick and dirty assembly code instead; and given up
as hopeless.

Stuff like this:

==One former machinist said he took Bezos up on his offer, made to the
entire company, to approach with ideas to become more efficient. But
after he pitched Bezos and returned to the factory floor, he said, “two
of my managers chewed me out and said I was going behind their backs.”
==
is way too common in so much business and government...

I quit going to "employee reviews" and submitting items for "future
budgeting and purchase." It was just a complete waste of time. The
"company" already had something in mind and my input would make no
difference to what was planned.

Some of us grow weary playing this game...

Not NPR, rather KUOW.

And Mazda admitted it was their flaw; they should have ignored a file without a suffix.
