Nissan knows you're sleepy, sends a scent to keep you alert

For those drivers tired of depending on triple mochachinos to keep them alert during long drives, Nissan is about to introduce a new method of bringing a drowsy driver back to alertness.

It's new Fuga model will be equipped with an attention assist system that will inject a burst of fresh forest scent into the a/c airstream to reinvigorate the driver when necessary.

The feature is only part of Nissan's innovative approach to driver safety.

The company recently exhibited a concept car that uses a facial recognition system to watch a driver for signs of drowsiness, as well as an odor detector sensitive enough to tell if there is alcohol in the sweat on a driver's palm.
