I like how your passengers will comment on your driving.
Your dates (at least from what I've seen) will only comment if you drive recklessly and hit stuff--and none of it is positive.
Your buddies, if you drive fast and skilfully, will make comments like "If we're going somewhere we may as well do it at pace.." Brucie gets quite animated the faster you drive and the more risks you take (splitting lanes, running lights etc.). If you hit something or something hits you, they'll curse out the other guy.

...No, I'm not very creative when it comes to this sort of thing.
