Earlier we met the Liebherr T284, which is an enormous big dump truck.
You were wondering how such a behemoth is controlled? Surprisingly easily. Wheel for steering with, go faster and go slower pedals, switch for going ahead or astern (looks like a gearlever but there aren’t any gears, because electric drive) and a joystick for tipping. That’s basically your lot.
Oh, and two cupholders.
