I have noticed that while fleeing from a high wanted level, it is good to use some of these tactics found here, but my friend also mentioned that it is harder for the police to find you if you switch vehicles when you have wanted stars.... Granted - you have to get out of the car, and switch vehicles while they are chasing you, all without being seen doing it (or killing the previous car owner (I would assume)).
I have tried testing this, but at higher wanted levels, the difficulty of this task increases.... Can anyone verify this for me? (I also saw someone mentioning it in a comment this on that linked question above - but I am looking for confirmation on the subject)
