Toyota's released a series of videos explaining how some of the features on the new Prius work — everything from how to turn on the headlights to how to use this, the solar powered ventilation system.
Basically, the system circulates air while the car's parked. Pretty trick idea if you ask us — especially given how much drivers reportedly love their own scent. Also, it has the added benefit of releasing any of your trapped (and obviously quite sweet-smelling) gaseous rectal emanations back into the environment. Ah, the sweet smell of fresh air! [via Toyota]
