How did Flávio Bolsonaro use 4 decoy cars to flee Brazil for US?

Flávio Bolsonaro fled to the US after losing Brazil election to Luiz Inácio Lula da Silva. Four dark-coloured cars left his home in Brasília and split in different directions to make it difficult to track him. He then crossed the land border into Argentina on Tuesday before boarding private jet that stopped in Ecuador to refuel before continuing to US.
