Por conta da pandemia, a Alemanha estava oferecendo o dobro de incentivos para compras de carros el\u00e9tricos, e para aproveitar, um alem\u00e3o queria trocar seu Ford Kuga por um Tesla Model 3 com piloto autom\u00e1tico, o modelo de entrada da montadora de Elon Musk.<\/p>\n\n\n\n

He then proceeded with the purchase, added his details and credit card, and clicked \"confirm\" to place the order with Tesla. But nothing happened; the button continued as it was, no message was shown, nothing different that could indicate that the order was being processed or even that it had already been placed or denied. As a result, he clicked again, as it might simply not have gone. And again, and so on 27 other times within two hours - what a persistent person!<\/p>\n\n\n\n

Ap\u00f3s as v\u00e1rias tentativas, finalmente o site deu sinal de vida e processou o pedido - por\u00e9m n\u00e3o apenas um, mas todas as 28 tentativas, totalizando 1,4 milh\u00e3o de euros pelos 28 Teslas Modelo 3. N\u00e3o apenas isso, mas caso o alem\u00e3o pedisse pra cancelar os 27 pedidos extras, ele ainda sim teria que desembolsar 100 euros por cada cancelamento, totalizando 2700 euros a mais do que apenas os 100 euros de dep\u00f3sito esperados pelo pedido de apenas um carro.<\/p>\n\n\n\n
