Ease of Tracking Your Movements
Most upscale electric vehicles like Tesla Model S or Porsche Tycan have advanced infotainment and driving aid systems as standard equipment. Tesla even has the infamous autonomous driving system, which has proven to be far from perfect, resulting in many crashes, even some fatal ones (via MOBI).
Those systems are designed to track your driving habits, locations, charging points, and so on. Are you sure that you want your every move to be recorded on a server?
