Ford Model T
Once the engine is running, the driver now has to make the Model T move on its own.  Step on the pedal all the way to the left, move the throttle lever to "give it the gas" and gently move the floor lever forward. This is low gear, the powerful gear used to get the Model T moving. Once it is moving, move the right lever up, let the left pedal come all the way up, and give it more gas to shift into high.  To make the car go faster still, move the throttle lever as well as the spark advance lever. Stepping on the left pedal only halfway puts the car in neutral, the same as the lever. This helps the Model T come to a stop without causing the engine to stop as well.
