The reporting in the UK of runway states on the atis came about as a result of an incident at Southampton in Oct 98 (see
http://www.aaib.dft.gov.uk/bulletin/jun00/gukfn.htm ).
While I realise that there is a difference in reporting criteria, it would take a braver man than me to decide that the runway is dry when ATC are reporting it as wet. Think of the concequences if you should go off the end (insurance/career etc).
