When you preview a game you don't get a full game to play with. You don't get to experience the same thing you do when you buy a game and do a playthrough. What you do get it what the game developer wants you to see. The rest of the information you get is given to you. You really can't form a true opinion of the game after a couple of hours of playtime and only seeing bits of it and that's why you write about what the game is aiming to be. With previews (both writing and reading) you have to keep an open mind.
With Undercover's review when I look back I'd actually consider it to be one of the more negative previews I've done and if I compare it to most gaming press previews, I'd say it was more negative than what you can usually read. I will however stand behind the things I wrote from personal experience. With the example you gave with Undercover - cars did in fact handle differently.
And as for SHIFT. I did a pretty personal preview this time and the reason being in the fact that I really was impressed with the game. So yes, you could call me a fanboi here
