|Mechanic Mark Buche says he sees one or two vehicles a week with rodent damage like this brake sensor wire.|
At some indefinite time in the distant future, a salesman is tasked with demonstrating his companies latest electric runabout (scooter?) to a primitive population. The 'natives' don't care for anything his hi-tech society produces, they are getting along just fine, but to humor the salesman they arrange a race between him and his scooter and one of their people riding some kind of animal. The salesman is sure of victory and a sale until his scooter won't start. It seems some kind of 'bug' has eaten the rhodium rotor out of the motor.
One other facet I remember is the salesman goes into one of their dwellings for a meeting and, given that they have different standards of cleanliness, the stench almost makes him gag.
