Why do motorways have three lanes?

Driving along a three lane motorway, rule 264 states that "Always drive in the left hand lane, except when overtaking". When driving in the left hand lane, I have often wondered why TWO overtaking lanes are needed. Is there a reason?

I've always understood that motorway X signs surrounded by a red ring are mandatory, so if you don't obey them, you deserve what you get. However, I have also seen these signs without the red ring around...
I read that if your tyre blows out when driving on a motorway you should never brake but go to a lower gear and try to steer the car to the hard shoulder. Is this sound advice?
