This is reinforcing the Ugly American meme. The Queen was not amused when our Secret Service demanded a helicopter land on her lawn when Obama visited.
Once again we have a president with no sense of dignity whatsoever.
The article says Obama took his armored car when he visited. But then I don't see him riding with the queen, as much as he hated the monarchy.
It also says Putin and Xi rode the 'golden carriage', so I guess we can change the term from 'ugly American' to the 'ugly non-brit' meme.
