Shortly after 5pm on the 29th of April I was cycling from the Imperial
War Musuem at Duxford to Whittlesford railway station.  As I came up
the A505 towards the M11 junction, the road was a dual carriageway.

Several cars and two or three motorbikes passed me without incident.
I looked at my speedo which indicated 25.6kph.  About halfway up the
slope, one particular car passed me very close by, at speed, with mere
inches to spare.

I shouted `too close', and was rewarded with a one-finger rude gesture
by the passenger.  The car drove off up to the junction and appeared
to leave on the slip road onto the Northbound M11.
