Nissan Helps Pedestrians Hear Electric Cars

Nissan keeps the safety of children, elderly, and blind pedestrians in mind as it designs its new electric car, the Leaf.  It breaks from the tradition of other near-silent electric cars by installing a futuristic sound.  According to Bloomberg News:

The company consulted Japanese composers of film scores. What Tabata and his six-member team came up with is a high-pitched sound reminiscent of the flying cars in “Blade Runner,” the 1982 film directed by Ridley Scott portraying his dystopian vision of 2019.

You can hear the prototype's whir in the Blade Runner video clip.
