Before this switch was thrown, we didn't have in-car navigation systems giving turn-by-turn directions, because back then, GPS couldn't tell you what block you were on, let alone what street.
Antes de desactivar el interruptor, no teníamos autos con sistemas de navegación integrado que nos dieran instrucciones en cada esquina, ya que entonces, el GPS no podía identificar en qué cuadra nos encontrábamos, ni siquiera en qué calle.
