so, from what little I know, and I’m absolutely not even remotely a car person:

car electrical systems run at really high voltage with much harder systems than you’d find inside a normal computer, because it’s an extremely noisy environment that has to survive lots of fucked up shocks

and AFAIK the standards are only kinda-sorta standards. interfacing with them is very very hard. im sure this gets easier once you get TO the network, but flashing that shit and changing what it does with the network seems like a pretty tall order. maybe try swapping out something near the cellular chip itself? that’s probably a pretty standardized part, right?

hard disk drives do still exist, and are useful for some stuff. mostly they’re cheaper. I think better for stuff you write to often?

SSD’s can overheat. but, again, there are usually sensors to throttle them when you’re in danger of this, and this idiot probably disabled those. because safety is for cucks i guess.

it is a thing, but any competently designed computer should have things in place to prevent this.

unless you’re an arrogant dipshit and disable all the hardware safeties on your computer to make it go faster and wear harder.
