Electric Scooter
Dog
The canine propulsion system varies dramatically by model. The Greyhound, nature's sports car, achieves speeds of 72 kilometres per hour in short bursts that would make any scooter weep with inadequacy. However, the average domestic dog cruises at a more modest 20-25 kilometres per hour and maintains this for approximately three minutes before discovering an irresistible smell.
The dog's speed is fundamentally unreliable. Direction is determined not by the operator but by squirrels, other dogs, and invisible scents left by neighbourhood cats in 2019. What the dog lacks in consistency, it compensates for with enthusiasm levels that border on clinical.
