A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

Why don't cars have diagnostic software loaded onto their infotainment centers? (lemm.ee)

Modern cars have MASSIVE digital displays, loads of computers systems monitoring every subsystem and internal diagnostics running to the OBDII ports.

Why the hell can't we get diagnostic feeds on our console or infotainment center?

I'm not aware of any car manufacturers selling their own diagnostic ASICs, so it's not an extra margin to squeeze afaik...

What gives? Any insight into this beyond the usual muh corporate profits conjecture?

Some cars do! Mine shows diagnostic info for the can bus and GPS by holding down a "secret" button combination. I'm sure other manufacturers do that too.

I can't even get my manufacturer to give me a fuse box diagram.. what make do you drive if you don't mind me being nosy?

2004 Honda Accord Coupe. Yup, screens even back then. (On the fancy models)

It's... a trooper. First thing I did after I bought the car was purchase the service manuals for $400. It's so easy to maintain.

I looked that up for my partners newer car. Annual subscription to a service manuals is $1500+.

Eish, that's horrible. Knowledge about the tech you paid thousands for should NEVER be a live service.

I'm about to go back to horse and buggy.
