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?


And exactly where is this 40mph on the M4? Perhaps where it passes
through a built up area in London, where the lanes are narrow and it
twists with frequent junctions?

I drive the M4 regularly, between central london right out to Wales.
The only place I can think that such a limit exists is where you get
close to London, and there are very good reasons for the limit at that
point.

Some more information on where your 40 mph limit on the M4 would be
useful in determining whether it is justified and thus not a valid piece
of supporting evidence; or not.
