It apparently started with European cars, and then was adopted by certain GM products, and has now found its way to the 2008 Dodge Avenger – tap the turn signal stalk and it executes three flashes and then stops. It’s useful for frequent highway lane changes, but subsequently in the Dodge the on/off detent on the signal stalk is almost impossible to determine. Minor? You bet. Annoying? You bet. Overly detailed quibbles aside, the Avenger carries on with the Dodge/Jeep theme of putting secondary radio controls on the back of the steering wheel. That great idea is right up there with putting the brake pedal behind the rear headrests.
