I always thought it was a speed sensor related to the speedometer. However, last week i went through one of those touchless carwashes that blows the car dry with a big fan at the end. When the fan passed over the rear of the car, the spoiler came up automatically. Is it an airspeed sensor close to the spoiler, or just a fluke?
