Peel microcars were built in Peel, Isle of Man in the 1960's by Peel Engineering. Two main models were produced in limited numbers: the two passenger Trident and one passenger P50. At just 54 inches in length, the P50 remains the world’s smallest production car
"The rickshaw, a two-wheeled human drawn passenger cart, appeared in China in the mid to late 1800s. Their popularity began to decline in the 1920s and by 1950 and the founding of the PRC most manual rickshaws were gone, perhaps in part because they had become a symbol of oppression of the working class. But the two and three-wheeled cycle and other animal and motor drawn vehicles are still in use today."
