London, 2015: Red London

Double-decker buses are in common use throughout the United Kingdom, 

and have been favoured over articulated buses by many operators 

because of the shorter length of double-deckers and larger amount of seating capacity; 

they also may be safer to operate through the narrow streets and tight corners common in Britain. 

The red double-decker buses in London have become a national symbol of England and United Kingdom.
