It’s difficult to prove anything like that. From independent research we know that Intel, and likely AMD too with their counterpart, can remotely control your PC via IME. But they’ve never done that yet or have done so very secretly, because then a lot more people would know and that would be problematic.
Personally I think it’s reasonable to suspect that Microsoft has full capability to severely cripple your system at any given time. Maybe not ‘brick’ as that may be impossible without proprietary hardware inside the machine. However, even a simple Windows installation can mess up your UEFI. Given that, do you think that all those millions of fully secret lines of code cannot render you unable to use your PC, even if just temporarily?
It’s not people driving poorly, as much as it is horrible city planning, poor traffic design and, perhaps most importantly, not requiring people to be educated enough before receiving a driver’s license.
This is an issue seen practically exclusively in underdeveloped countries. In Europe road accidents are incredibly rare. Nobody here even considers self-driving cars a solution to anything, because there’s nothing to solve.
This is nothing but Tesla (et al.) selling a ‘solution’ to an artificially created problem, that will not solve anything and simply address the symptoms.
