Hmm, I've always wondered what those stars mean, but I'm still not much wiser. And I've been playing since the start, having one star. Exactly. Did the same thing. Tuned my Bentley so it handles like a dream and was always up in front after a couple of turns. Then slowed down drivatars until the score was on our side. Only had a problem with the highway race, one slipped through and I couldn't get him. Overall a good strategy, but I've seen the dirvatars do it before as well, so I'm afraid, we are teaching them this tactics as well.
