Toyota is traditionally a conservative company when it comes to adopting new car technology, which makes this recent patent it filed all the more hilarious. Just like the headline says, the patent includes a system that will release tear gas into the car. The noxious gas is piped in when the vehicle detects an illegitimate engine start. Now if that's not the most metal thing you've seen out of Toyota in a long time (forever?) we're not sure what is.
This section of the patent is part of a larger scheme of patenting a fragrance system similar to Mercedes' where you can choose the scent you want pumped out of the air vents. It's a novel feature that can help cleanse the cabin of any unpleasant odors, but can get annoying with strong and prolonged use. Toyota's system would theoretically be more seamless and personable than anything currently on the market, because it's designed to automatically detect who is getting into the vehicle via their mobile device. It will then dispense that driver's preferred fragrance.
