There’s a very important part of your vehicle that most people don’t ever think about.  It’s called the Differential and it allows your engine to drive wheels on opposite sides of the car at different speeds, allowing you to go around corners without destroying your tires or axles.  The concept is exceedingly simple, and while it’s been enhanced quite a bit over the years, it’s not too different than what General Motors demonstrates in this video from 1937!  Some engineering designs are pure art. Even if you’re not technically-inclined, this 8-or-so minute video puts it in layman’s terms and it’s fun to watch!
