One often over looked aspect of EVs are their relative fragility compared to a ICE vehicle. I see it as an analog/digital divide. You can get an ICE to temporarily run with all sorts of deficits, incorrect inputs, or hacks. It will still kinda work. EVs are way more digital. If one thing in the chain breaks the bit flips to false and you're done until the tow truck comes and an expert with special, secret knowledge and tools can disassemble it and flip the bit back to true so to speak.
