Straight out of John Norman's books. There's an affordance for leaving th= e keys in the vehicle, and no forcing function to prevent it. In ham radio we are supposed to use the minimum power needed to make the co= ntact. On most radios there's a power setting control. If you can't make the hop = you crank up the power. A nice forcing function.
