The NTSB proposes to require cars to have wireless communication systems.

There are two dangers here. First, we already know that many car systems have bad security, and many wireless systems have bad security. Anything like WiFi in a car could enable someone to cause a crash.

Even if the car does not turn out to have this problem, it could prove to be an excuse to deny car owners control over any of the software in their cars -- even the software in the entertainment systems.

Second, if a car can be identified from its transmissions, this will become another surveillance system for tracking everyone.

We must insist that the design be such as to avoid both of these sorts of problems.
