Looks like a huge security threat IMO considering these are huge batteries moving at 70 mph. Considering these have cameras and autopilot, a compromised vehicle can be made to malfunction next to a truck or something to inflict maximum damage.
And this is without even going into all the intelligence threats considering many of the owners are high net worth people probably in constant contact with important people in government and can have access to priveleged info.
With that being said, it's important to compare with other connected car implementations by competing OEMs and point out if they have similar vulnerabilities
However, on telas scale, I would properly have multiple in different countries.
