my repeated fantasies are a blind person with a reinforced version of their stick, using that stick to great effect to damage cars that are parked on the sidewalk. like, when they bump into a car they take the stick an beat the car for all that its worth creating as much damage as possible.

the other fantasy is carrying a bazooka and shooting anyone speeding. optionally the weapon is futuristic and able to just vaporize the car while leaving passengers unharmed. they just suddenly find themselves sitting on the street looking dumbfounded.
