"Super-fast" Broadband From BT?

Don't make me laugh:

"Telecoms provider BT is accelerating its fibre broadband rollout. It now plans to offer "super-fast" internet speeds to two-thirds of UK premises by the end of 2014.

The target is a year ahead of its original plan.

The firm says its main product will offer maximum download speeds about 10 times faster than at present, at 70-100Mbps on average....

...A recent report suggested the UK ranked 25th in the world in terms of average broadband connection speeds.
Akamai's State of the Internet Report said the average UK connection speed was 5Mbps compared to the Netherlands' 8.5Mbps and South Korea's 13.8Mbps."

How about BT making sure virtually ALL premises have a minimum speed somewhere close to the average first?
My connection speed has recently increased by 30% - to a sloth like 1.7Mbps, so it only needs a threefold increase to reach the rather low average the UK currently suffers & a speed twenty times faster to reach what the favoured few elsewhere will receive.
Yet I'm paying exactly the same price for a far worse service & changing ISP's wont alter this, as it is poor infrastructure (BT's domain) to blame.
