Sticking ONLY to speed limit signs, do you not think that with
the ever increasing number of them, drivers are simply taking
less notice of each of them individually ?

That's because many of the limits are arbitrary, and in particular are
generally not lowered at specific hazards. In France, however, if a
bend on a 90kph road requires 50kph, that's the limit that is imposed,
often with an intermediate limit to give a smooth reduction in speed.
With intelligent limits like that, I find I am much more inclined to
obey them than the blanket UK ones.
