Or you could just buy a Ford S-MAX with an automatic speed limiter built 
in.  I found this on a 30 second web search in response to PBL's 
comment.  I have no idea about the safety argument for this feature.

The point is more that all sorts of things are being automated or 
semi-automated in cars.  The world is changing.  This change will happen 
with us or without us.
