The MIDAS [0] system used to set dynamic speed limits can make for some frustrating driving.
A few weeks back I had a journey on the M42 at evening rush hour where the dynamic speed limit was frequently cycling between NSL -> 60 -> 50 -> 40 -> NSL. Each limit was enforced for 1-2 gantries.
Even to someone who understands the benefit of dynamic speed limits for ensuring good traffic flow, it's not a good experience.
