Remember folks, filing a patent doesn't ensure implementation. If Ford starts snooping on our in-car conversations and injecting ads into our Spotify streams, we can just refuse to buy Fords. They know this. The patent actually makes it less likely that other companies will copy them, so we're less likely to end up in a situation where we have no choice.
Now if the NHTSA mandates that all new vehicles come with in-car microphones and AI to listen to conversations to stop drunk driving or some other crazy reason, we're in real trouble. That's why we have touchscreens in every car now - backup cams are mandatory, and if they have to have the screen, they'll use it for everything.
