I'm torn on if i'd even want to setup this type of anywhere connection to my vehicles. On one hand, remote configuration, updates (maybe just use uptane?), and debugging is attractive, but the other hand is now you have a new threat vector that can cause a lot of harm if exploited.
Many people think that this is an issue that needs to be solved before self-driving vehicles are deployed at scale. We need to wake up and realize the degree to which the vehicles we drive TODAY are vulnerable to remote exploitation. If the vehicle has an internet connection, there's likely a vulnerability somewhere. An attacker may not be able to drive it to a specific location to crash, but they can disable critical safety systems and crash it all the same.
