There are a lot of people that are dependent on their car, but don't know much more than how to turn the steering wheel and push the gas/brake pedals.

True (I knew that would come up). But I don't need to know how TCP/IP works to write a web page. Likewise, most people know how to put gas in their car, and some can change their oil, antifreeze and tires. There's a difference between zero-knowledge, and working knowledge.

I am not quite sure at what points these types of knowledge are equivalent.

And that's exactly the way it should be.
