Haven't noticed much said about the TT's so far, so thought I would give it a shot...

The number of tracks available is amazing!  Also, each track you might choose has multiple versions (like GP, International, etc) and also seems to have multiple car styles as sub-categories, so each Time Trial is specific for each track and each car, which adds to the massive number of TT's you can choose from.

I chose to try out Oultan Park International (familiar to me from earlier races in Career Formula Rookie) and used the "stock car" option.  Surprisingly, with only a few try's, I ended up in 14th place on the record list - but 7.5 seconds behind the fastest guy.  I guess there are so many TT races that it's hard for all the fasties to have tried them all out just yet.

So - give it a shot (Pippy, SLC, ExTex, anyone).  Go ahead and show me how slow I really am!
