Have fun explaining why there is a push to sell high
end cars too, when those dont even have an OS.

Yes they do.

No they dont. Thats not an OS, thats just the code in the
electronic controls.

You need to read up a bit.

You need to take Bull****ting 101.

OS needn't mean something like Windows or Linux or even DOS btw.

No one ever said it did. There is however a
difference between code in a computer and an OS.

AND even if cars did have OSs, and they dont,

Your info is out of date.


that is not the reason car
manufacturers make more money on the more expensive cars anyway.

I never said it was.

It's to reduce amnufacturing cost.

Nope, you wouldnt know what an OS was if it bit you on your lard arse.

I never said you did. It was that fool desperately cowering
behing SMS that made that stupid pig ignorant claim.

Wrong, as always.

This is right from your reference.

"An operating system (OS) is a computer program that
manages the hardware and software resources of a computer.

And that doesnt happen with engine control
systems in cars, most obviously with the software.

Cars have more computers than just the ECU now.

Still dont have an OS in the absolute vast bulk of them.

That's not what the claim was.

You said no cars have an OS.

You're completely wrong.

That's really the bottom line. Newer cars definitely do have computers
that are running a RTOS, often more than one. It's very different than
the older vehicles that had only an engine control unit that ran some
micro-code. My relative that owns a repair shop just went to a Toyota
class on electrical systems where they were teaching the mechanics about
the networking system on the newer vehicles. The OS is more to tie the
different micro-controllers together than anything else. Each
micro-controller is for a specific function, I guess they want to keep
things distributed for now. Makes sense, with micro-controllers costing
under $1 for the simpler ones.
