So, I'm going to be a voice of reason here, also working for a a major US automaker: there's a 0.0001% chance this would ever be a thing implemented, and is almost definitely just something someone brainstormed and threw in the patent/IP registration system for a nice bonus. We're heavily encouraged to submit ideas, even if there's no real plans to ever implement them, and you can make more than $2k for a couple day's worth of work in some cases.
I've come up with some hilariously dystopian ideas, and I'm more than happy to submit them because I know we'll never bother with implementing them, it keeps other more "ambitious" OEMs from doing it, and the aforementioned monetary bonuses. Just because something is patented, doesn't mean it's going into production next week.
Also, because I know what sub I'm in, before everyone crucifies me here because I work for an automaker, I do so because I want to make a change from the inside, and my job focus is primarily on making vehicles safer for pedestrians and cyclists.
