So today is the second tube strike in London in a week. As of 8.30pm last night, the Tubes shut down, and they won’t reopen until tomorrow morning. This leaves cars, cabs and buses as the only options for getting into the centre of town. And of course they’re completely overwhelmed with extra demand. Getting into Central London today is essentially a waste of time. If you don’t believe me, then read the BBC strike survival guide or wander through a huge list of London traffic web-cams.
