Vehicle electronics have turned into data-collect centers.
Everything from location to conversations to driving habits to passenger devices are collected. Including biometrics which will be used for future identification.
And yet the buyer/owner is unaware.
This should be "opt-in" by law. A known mutual agreement. And the terms made clear at time of sale.

Other bits of information about you and your passengers can be collected automatically, when you’re just sitting there. Because while your car is waiting to respond to your command, its sensors are, uh, “sensing”. That’s probably why vehicle data hubs, the data brokers of the car industry, can brag about having so many data points like driver fatigue -- which monitors head and eye position -- and heart rate.
Another way your car collects data is from the connected services you use from your car’s dashboard, like satellite radio or a GPS route planner. Then there’s the devices you connect to it, like a telematics device: a plug-in that sends information about your driving behavior to your insurance company, or your phone. Car companies can also get data about you from your phone when you download the car’s app.
