Digital inter-vehicle communication, what can possibly go wrong?! I hope, they get the security right.

  To get any network security right, you have to start with the assumption that each node is fully open to being controlled/modifiable by its end user, and that there is a non-negligable amount of unaccountable trolling nodes that will actively seek to disrupt the system. In the world of corporate embedded design and agency approvals, how likely do you think this is?

    Look at flaws in aviation communication systems like ADS-B. This is highly regulated territory and full of agency approvals. With car owners as customers, the manufacturers will need to build the onboard units as cost effective as possible. I doubt that they will develop hardware and software from scratch in order to employ maximum security.

      I wasn't using "agency approvals" as a positive point for security :P. Real security properties just aren't legible to that kind of environment. Most likely they'll start off with some "tamperproof" microcontroller platform to assume away user control, further rely on keeping the protocol documentation secret and other obfuscation, and then write naive code that trusts every node to behave because they can't conceive of how brittle that kind of system is.

    Oh god. Advertisers! "It's late, time for fourthmeal Taco Bell ahead on the left." No no no no.... Don't even open that door.
