I'm Cut Off

Deciding to live as far east as it is possible to live within the United Kingdom I do appreciate that I must expect to face some difficulties when trying to drive to anywhere else within these islands. But can someone explain to me why a journey from Lowestoft to the centre of London, which is approximately 103 miles as the crow flies should take over 3 hours. I would also love to hear from anyone who can tell me why most of the people who have lived in this area all their lives, actually appear not to care about being cut-off from the rest of our nation.
