People who see you a half mile across the parking lot and decide to hold the door open for you
forcing you to either break into a brisk trot or let them wait until you're almost there and then they give up and let the door swing shut...
Traffic lights that try to combine right turns and pedestrians at the same time. As the light changes to green, all the waiting pedestrians cross en masse, forcing you to wait, and then the light turns red again...
Electric cars that cost more in energy wasted and less value per mile than they could ever hope to amortize or justify by the amount of gasoline used or not used.
