Just proving the point that even so-called professional drivers get it
wrong on straight roads in response to the posting about people
crashing because of speed cameras, as to the effect on speed, I
understand the average speed cameras,which do discriminate between
vehicle types and employ ANPR are very likely to receive central
funding following highly successful trials on the M4 in the West and
in South Wales.

Average speed cameras have been in use in a number of locations for a number
of years. The oldest installation I know of is in Northampton. There's an
installation on the M3 that has been there a couple of years now. So what is
this trial on the M4 for?
