Hey, I think this site is amazing and certain appeals to my "hacker aesthetic" even though I'm not a car person! One thing that I'd like to see is some kind of guided tour - I got to the page and instantly saw "how heating systems work" and then "the engine - how power is created" and this confused me a bit. It made it seem like the first thing you need to know about cars is how the heater works!

Then I realized there wasn't rhyme or reason about the order of the Basics and I kind of got a bit of the tyranny of choice and then came back to the Hacker News article.

I feel if there was a path for first time visitors I would have taken it and been lost in engine parts for the rest of the day ;)
