So from the speeding thread - and some Googling from that.
It's illegal in Western Australia to drive slower than 20 km / hr under the speed limit on a freeway unless you there are good reasons

Never knew that. Didn't need to know that. But I learnt that from an MN thread today.
So what random facts have you learnt from MN recently?
