Do excuse my ignorance. So to summarise the words of enlightenment in this thread...
The new speed limit will be 30, unless its outside a school in which case its walking pace, unless its a secondary school in which case its 90 (Natural selectino). If the school is on a dual carridgeway, its 70, unless there is no a central reservation, in which case its 60, unless its during the summer holidays in which case its 90. Easter holiday its 85, because this holiday moves and people will get it wrong. And killed.
Motorways, its a default of 90-120, depending on the mood of the variable speed limit operator. If there are clouds its 20, and if theres fog you should pull over. Snipers will be deployed to eliminate lorry drivers who dare to overtake each other and nervous drivers will directed into the hard shoulder to await death. Boy racers will be encouraged to drive at 90 (Or 95 if they have an induction kit) at all times and in all weather, on the condition that they only crash into each other.
Have I missed anything?
