Did you know all electric, hybrid and many luxury gasoline vehicles are by wire control? I mean throttle by wire, shift by wire, brake by wire (electric over hydraulic with manual backup) and steer by wire (mostly high torque electric assist with direct manual connection). Did you know most new vehicles have a satellite uplink for in field data collection? This data collection includes CAN bus signals and geolocation (lat, long, altitude). I can request data for every vehicle platform I work on that shows an overheat condition while driving up Baker grade (Baker, CA to Las Vegas) and get any vehicle data channels I request. Your vehicle VIN is broadcast on the vehicle CAN typically once per second. Why? I have indirect access to this data for in service fleet and field issue resolution. I am not supposed to know how much data is collected or can be collected but I can request and get any customer data broadcast on the CAN bus under my defined conditions. I don't know if this data is saved by default or only collected by specific request. I used to joke with my coworkers 15 years ago that we didn't need to go to work to test vehicles because all I needed was a laptop and an OnStar uplink to drive from home. The data broadcast on the vehicle CAN bus today combine with a satellite uplink is enough to find your vehicle, see where it is and in theory take control. Most people know about Event Data Recorder (EDR) data collected during airbag deployment which is slow 0.5hz and very limited but almost no one is aware of satellite uplink data. You probably signed a data disclosure when you bought your new car but didn't really understand what it meant. Can someone take control of your car? I don't know but everything is in place to do so except maybe an interface between your car and my laptop but IDK. I prefer to drive manual transmission vehicles.
