I'm writing about a cryptomancer who enherited a 1938 Packard Eight Coupe from his grandpa (also a wizard). He calls it The Experiment. I've come to a place in the story where someone other than the Protagonist has to drive, they look down at the floorboards and see seven pedals. I want there to be seven, the number seems right, but I can only think of six uses. The universal antiphase pedal The clutch The brake The brake mass-effector The accelerator mass-effector The accelerator The Experiment also has a range of features, like: Instantly hot heater and instantly cold AC, A gear shift for lateral movement, front wheel drive/rear wheel drive/4 wheel drive, and a "snap horizon" lever which plumbs the car to the surface of the earth. So I need help coming up with a seventh pedal, and if anyone has an idea for a feature that seems useful that would be great to see as well.
