At EVS26 this week, Ample International of China presented its imminent eZero billed as "the World's Smallest Electric Car" It weighs only 550 kg and, with lead acid batteries, has fast charging and 200 km range.
Four people were shown inside it: they were in intimate contact. Note the surprised expressions. It will be launched in China and later in the USA at "around $6-7000". Unfortunately that gets you two all-electric Tara Tiny cars from India or two golf cars. Back to the drawing board.
