courtesy run

while waiting to cross the road a kind motorist slows down and indicates you to cross: whilst the actual speed of the run across the road is the same as walking, the illusion of hurrying engenders a feeling of good will between motorist and pedestrian.

Friend A: What the hell was that?
Friend B: That was my courtesy run!
A: But it was no quicker than walking!
B: Yeah but it makes drivers feel better
A: Cunning
B: Like a fox!
