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.

  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?

Yo it'd be sick af to root your cars dash and load some OS onto it and have your own console!

ODB2 into a raspberry pi or a breadboard somehow, get some sick diagnostics application whipped up.

Here's to projects I'll never tackle.

I had an old Android tablet running Torque in my dash where the radio used to be. Adapter and phone app, $20.

I have a couple of those OBDongles that pair over BT, honestly the interface leaves a lot to be desired.

My 2015 Mazda 3 is rootable. Then Mazda made them unrootable with an update, and then the leet hackers started physically opening them up and rooting them with UART.

Hondas infotainment is just android. And at least on my friends 2017 Civic you could get to the regular ass android interface. Most of them are some flavor of Linux.

Also you can install whatever head unit you want on most cars. You can even buy a head unit from china that will match your cars trim for like $300 from china.
