khaobadi yes i have to agree. But still i have read in the newspaper that new york and london are the most compared city in the world as these are considered because of being economic capitals of the world . i dont think any american city can be compared with london as that may not withstand londons economy People who have been to europe, england and america has said that transport in some european cities are considred the best particularly country like switzerland and scandinavia.but still london is considered as best and overrated. but still best is the general verdict.
