           | Not that I am any sort of expert on the subject, but the way
           | I understand it is:
           | 
           | 1. If you have a fossil you can carbon date it based on the
           | amount of C14, which is an isotope of carbon, and is present
           | in relatively stable amounts in living organisms. That's
           | because a living organism takes carbon from its environment
           | and then incorporates it in itself and C14 is continuously
           | generated in the environment because of the radiation from
           | the sun. As the organism dies, the intake stops, so then you
           | can determine its age based on the half life of the C14 and
           | the amount of it still remaining in the remains. Long story
           | short: it cannot be accurate.
           | 
           | 2. You can only measure this in remains of dead organisms.
           | Maybe in leather, if the car had some, otherwise I don't
           | think you could easily carbon date a car :)

       | It'd be nice if some tiny pool of government resources
       | (everywhere) were set aside in 'untraceable' ways that only
       | someone from many years later could use, by which time any
       | untapped resources would be rolled into a new investment area or
       | returned to the general fund.
       | 
       | The non time traveler version would be completely off the books
       | spy operations, so plausibly someone might rarely need that for
       | non-time traveler reasons and thus hide any time travelers.

       | see a movie, and not a very good one either.
       | 
       | If you have a quick layover somewhere, make it interesting - I

       | These may not be best practices, but they are enjoyable
       | practices, and someone able to access all of time and space that
       | doesn't attempt to enjoy themselves has definitely something a
       | bit wrong in the head - just saying. Lucky this guy found someone
       | to order him around in his life.
