Dave Plowman (News) ( snipped-for-privacy@davenoise.co.uk) gurgled happily, sounding much like they were saying :
KPH, Dave, KPH. Conor's used to truck speedos, which are all in KPH.
Although I think that may be optimistic, too.
But, of course, since Conor *never* breaks a speed limit, even that'd be a guesstimate.
