VIEWPOINT - Don't Wave, Drive!
Some of the most dangerous drivers on the road recently are those that are trying to be polite by waving a second driver to go when that second driver doesn't have the right of way. Drivers should just drive to the rules of the road, its safer and keeps the traffic moving in an orderly fashion.
Unfortunately I think your current advertising, the hand waving thing, encourages the 'polite' rather than the 'correct' way to drive. Polite drivers also encourage aggressive drivers that are always trying to sneak ahead when its not their turn. These bullying drivers are depending on the polite drivers to enable their bad driving habits.
Folks should be encouraged to stick to the rules of the road. It's better for everybody.
