There's the old joke: "All those present that object to receiving speeding fines please raise your right foot". People object to speeding fines but receiving them is entirely optional. Personally, I'd rather they clamped down harder on tailgating, poor lane discipline and uninsured drivers than on motorway speed limits.
Its the "one size fits all" rule which annoys me. My car will comfortably sit at 110mph all day long, if I'm alone on a motorway in the early hours who am i hurting or endangering? It certainly isn't about safety because that same car will stop from 100mph in less distance than the highway code requires for 70.
