How about 40mph on the M4?

And no, I am not referring temporary limit at a set of roadworks
(even though 40 is still extracting the urine a bit, even at
roadworks). I am speaking of a permanent limit of 40mph on part of
the M4.

Do you not agree that such a limit is *way too low* on a motorway?

You're presumably referring to the elevated section of the M4 in London,
which has 2 lanes per carriageway, no hard shoulder, and very heavy
traffic flows. This is not a typical motorway, though I felt that the
previous 50mph limit here was adequate. Anyone know what the accident
rate was on this section before the 40 limit was imposed?
