This doesn't just apply to Tesla of course. You've discovered what is in most modern Infotainment systems. The car no longer belongs to the customer and is a source of continuous revenue for the manufacturer - at least that's the way the C-suite sees it. Early in my career I worked for one of the most popular car companies on the Infotainment team, and I argued for customer privacy and data on a daily basis with managers and other engineers. I was always the minority.
