Is it possible to look up historical traffic data?
I have a colleague who blames her absence from an important teams meeting due to a 'at a standstill for 2 hours on the M4' on Friday afternoon (she had a lunchtime appointment, but says she got home at 5pm instead of 3pm).
Quite frankly she has form for lying, and I think this was an excuse for not attending a meeting :-( .
Is there anyway I can find out if this big accident actually happened or not?
