Is it enough that the planners [presumably] don't have a tool to turn 
the hashed data into real cars (so they can for example spy on 
ex-girlfriends) or is it the danger that 3rd parties involved in more 
serious data leaks (legal or otherwise) potentially aided by specific 
attacks on the hashing, which is the bigger concern?
