Toyota is trying to go innovative by looking forward to introduce a personalized fragrance dispenser that not only gives out personalized scents according to the user, but also has the ability to spray out tear gas in case of a break in.

Earlier, automaker Toyota filed a patent for a personalized fragrance dispenser system that proposes a simple idea: when the car recognizes someone as an authorized user, it can spray out their favorite scent, but if the car gets broken into, it can spray out tear gas to make those thieves run away.

The system can detect when someone is walking up to them and spray their favorite scent out of multiple perfumes in advance and will deodorize the car after they leave, returning it to its neutral scent. In order to detect the person, the system relies on signals sent from a paired smartphone, explained Futurism.

Also, if the system detects an ‘illegitimate engine start’, it can dispense tear gas instead of perfume, most probably sending the thieve away. The deodorizer will be capable of removing tear gas from the car.

Though cars already have fragrance dispensers, but according to CNET, Toyota’s describes it as the first attempt to personalize, or weaponize, them.
