A few years ago the old "iconic" London Bus (the Routemaster) was phased out as it was getting a little old (being first made in 1954) in favour of modern alternatives. The replacement "bendy" buses proved unpopular because they just don't fit in the street space available. And now they are being phased out.
Their replacement is an Electric / Diesel hybrid double-decker (i.e. with an upper floor) which gets 11.6 MPG compared to the 4.5 of the bendy ones.

And a video of experts "drifting" buses, narrated by a man who calls his hands "hends" - from when we in Britain were "top nation".
