Several things. Firstly NPD is only the USA whereas this sites NA numbers include canada and Mexico I believe.
Secondly its a racing game, which generally sell well in Europe. So mainland EU may be skewing closer to the UK sales then most games usually do.
It may or may not be overtracked I haven't looked at the numbers but since this site adjusts on the fly it should sort itself out eventually.
