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?

Interesting fact. OBDII is a CARB requirement, so it’s tied to cars that must meet emissions standards. This is why Teslas don’t need to include one (ands it likely other manufacturers will stop including them in their electric models at some point as well). No emissions systems to check means no need for an OBDII port.
