If you don't know what it is, you are not the target audience and you won't become the target audience by suddenly knowing what a CAN bus is.

So you've never visited a web site, read a bit about a topic you knew nothing about, and then thought, "Wow, that sounds like something I'd like to get into?"

There are a lot of people out there who are curious about the world around them and enjoy expanding what they know instead of stagnating in a knowledge silo.
