Well, I was thinking of sort/merge and cobol!

It may be trivial in respects of a computer recording the 'reads' - but
clearly it is not possible to keep 'track' of each individual vehicle's
movements in any realistic way. In other words - the information may be in
the computer - but there are nowhere near enough staff available to
scutinise that information and make use of it.

Absolutely! The information is invaluable! Christ I can't believe the
naivety and technical ignorance of some of the posts here.

Explain how the information is invaluable - and explain how millions of
vehicle movements can be scrutinised individually.
