On Steering Wheel Pros: Easy to reach Won’t have to glance over Cons: Difficult to install 18
19
Ground Next to Driver Pros: Easy to place build Can be easily moved Cons: Driver must look down 19
20
Podium Next to Driver Pros: Easy to reach Adaptable Cons: More materials required 20
21
Side of Seat Pros: Buttons are easier to reach Eyes can stay on road Cons: Unconventional setup may confuse people Buttons not visible 21
22
Build ground setup first Quick build time gives us more time for testing Build Podium The ground button setup can be placed directly on the podium without much extra work 22
