Keep A-Spec and B-Spec driving distance statistics separate

[GBO Possum]

In GT5, my "distance driven" is over 40,000 miles. However, most of this has been done by my B-Spec drivers. The so-called "Bobs".

I'd REALLY like to know how many miles I have actually driven. And how long it took me.

It'd also be nice to know these statistics for each of my Bobs, although that's less important. An aggregate Bob total would suffice for me.
