Zonai Devices are a mechanic unique to The Legend of Zelda: Tears of the Kingdom, and are a major part of what separates the gameplay experience from Breath of the Wild. They are mysterious pieces of technology originating from the Zonai, a group of beings said to have been the first to roam Hyrule. One such device they left behind is the Steering Stick, which Link can use to drive vehicles around Hyrule. Here's how players can use Steering Sticks to control vehicles in Tears of the Kingdom.
What Is A Steering Stick?
A Steering Stick is a Zonai Device that allows players to steer any vehicle it is attached to. This makes vehicles far easier to maneuver as the player can now control the direction the vehicle goes. The definition of 'vehicle' is also very loose, as the Steering Stick can be attached to almost anything that Link can stand on.
How to Drive Using a Steering Stick
Steering Sticks are very easy to use. The player should first attach the Steering Stick to the front of the vehicle of choice using Ultrahand — car, raft, boat, etc. Then, as long as the device is usable, the Steering Stick can be used to control the direction the vehicle goes. It can be controlled by stepping onto the device and pressing 'A' to activate it.
It should be noted that the Steering Stick uses up the Energy Cell charge, so players should upgrade the Energy Cell if they want to drive for long distances.
Where to Find a Steering Stick
Steering Sticks are relatively rare, but there are a few reliable places to source them.
Zonai Device Dispensers
The most reliable, though difficult-to-access method of getting a Steering Stick is to use the Zonai Device Dispensers in the North Hyrule Sky and Tarrey Town Construction Site. By inserting 
Zonai Charge or Large Zonai Charges into the Zonai Device Dispenser, the player has a chance to receive a 
Steering Stick.
Zonai Devices Scattered Across the Map
As the player travels across Hyrule, they will come across random caches of Zonai Devices. These typically contain the components needed to make a boat, which includes a Steering Stick. These caches can usually be found along the sides of rivers. The one in the above image can be found at coordinates 2147, -2173, 0034, though there are many scattered across the map.
The Legend of Zelda: Tears of the Kingdom is available now on Nintendo Switch.
