OK, we know the bus routes are dangerous, so what's a viable alternative?
Well, last time we checked, incidences of piracy on the Thames were at an all time low, so Londonist would suggest getting a boat.
Thames Clippers already runs a daily service between Masthouse Terrace, Greenland (Surrey Quays), Canary Wharf, St Katharine Docks, London Bridge, Blackfriars and Savoy Piers, as well as the Tate-to-Tate (Damien Hirst-decorated) Riverbus; but now it looks like the service is set to expand pretty rapidly.
Of course, what Londonist would like to see is a 'taxi' style service of sleek, black speedboats, sort of like the one James Bond had in The World is Not Enough.
Imagine flagging one of them down in the early hours of Saturday morning! And it wouldn't matter if you were sick, you could just lean over the side. It's a winner we tell you.
