Automotive UX has always had to solve for complexity other industries are only starting to face. Chris Jacobs of 42dot and Eric Lee show what that looks like in practice, and why the lessons apply far outside the car.

You will see first hand:

• A haptic steering wheel prototype built with ProtoPie and Arduino, whose code shipped in a production Rivian

• One controller orchestrating a HUD, mobile phone, and tablet panel simultaneously

• An AI diagnostics dashboard connected live to the ChatGPT API, responding to real vehicle data

• Why most prototyping tools break beyond a single screen, and what to use instead
