I’ve mastered the ability, out of necessity, to shift while never removing my thumb from the horn trigger. This skill has been developed over a period of years of commuting on 4-lane roads. It seems today’s drivers are too preoccupied with cell phones and breakfast to signal their intentions before changing lanes. The tone of the Stebel air horn is akin to that of a semi truck. It tends to snap the focus of an errant driver back to where it needs to be.
Something for the Soul.
