If you had charge spots everywhere, and you had battery swap stations everywhere, how often would you do it? And it ends up that you'd do swapping less times than you stop at a gas station.
Se houvesse pontos de recarga  em todo o lado, e estações de troca de baterias  em todo o lado, quantas vezes o faríamos? Acabamos por trocar menos vezes  do que paramos numa bomba de gasolina.
