Biden Calls Chinese Electric Vehicles a Security Threat::The president ordered an investigation into auto technology that could track U.S. drivers, part of a broader effort to stop E.V. and other smart-car imports from China.
Why should every car owner have to also be a tech nerd or security specialist just to guarantee their car is safe to drive and own? They should be guaranteed safe before they are even sold.
Of course, consumers should have full control over the technology they buy, but it should be safe and secure before it is even sold in the first place. 
The only way to know it is safe is 3rd parties auditing it. The manufacture saying “trust me bro” ain’t it and a government audit that doesn’t show their work could be bullshit too. A single tech nerd or security specialist is in the same boat as the regular Joe - it’s a group effort. Non-techies can contribute in other ways (e.g. reporting bugs).
To be so transparent that we can actually verify the government’s findings means a 3rd party is doing the same job the government did. Anything less is the government saying “trust us”. [Edit to clarify what I meant] It’s cheaper for a bad company to pay for lobbyists or buyout a few politicians than to somehow buyout every 3rd party.
