What's the one single car part you don't understand on your car?

For me it has to be the helical differential. Absolutely no idea. :O

Why they sell Blinker fluid in 0.5l cans if my car only uses 0.3l.

But to be honest i don’t get vacuum system. i don’t get it how it works or why we need it in a car.

I drive a BMW, and I don’t understand that lever on the left side of the steering column, like why is it there?

i assume a helical differential performs the same job as a normal differential. The reason they use helical gears though is because they can take more force through a smaller size of gear. this works well for weight reduction and space that is avaliable. This works due to having a larger surface area between the teeth in contact while the gears are spinning. This spreads out the load (force) across the surface of tooth rather than on to a single point. Hope this helps a little bit.

a quick update doesnt save much weight this due to the fact that the helical gears create forces in other directions so the case around the gears need to be made stronger to contain these forces sorry for that bit.
