See penultimate paragraph!What though Colin?
If you force drivers to do (say) 40 mph for short stretches of road that can't be made safe any other way, that might not have a huge impact on journey times. Vehicles can safely drive much closer together at low speeds so you could probably get the same number of vehicles through per hour as on the faster sections where there can often be jams caused by panic braking.
I would almost be willing to bet that the average speed of traffic on heavily congested roads with a 40 mph limit is about the same as on a busy motorway because the traffic flow is smoother rather than stop-start all the time. That is assuming that speed limits are actually enforced!
