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?

ALDL was proprietary to GM kind of like apple and their connector tomfoolery. In 1990-something CARB probably didn't want to buy all the different diagnostic tools so they said if you want to drive in California your car needs OBD-II. Now, I can check and clear codes on any modern car with a $35 tool.
