Someone doing that is not interested in speed limits and just does their own thing. They don't seem to worry about the possibility of a police speed trap.
Known as the 40mph club, or the "FART" club (Forty All the Ruddy Time), also emphasizing that these people are generally older and lacking awareness and attention perhaps as a result of their extended years, and perhaps it's time to hand in their licence and stick to their ENCTS or equivalent instead.
