A British man drew inspiration from a child's toy mail car and made the world's smallest car, which is 39 inches (about 99 cm) high and 26 inches (about 66 cm) wide. The creation of this 47-year-old man named Watkins has been certified as the world's smallest car. It is reported that Watkins broke the record for the shortest car three times. His inspiration for building the world's smallest car came from children's toy mail cars. After seven months of modifications, the car was finally ready to go on the road.
