I just got myself 5 star and after a really lame 5 minute chase I evaded them pretty easy. I drove off the road in the city into the river/sewer system (still in open air) I then went down the traintracks and hid in the tunnel... No-one followed me but I was surrounded.
I heard a train approaching and got into one of the carriages and went 'prone'/hid
I lost all my stars.
I guess it's cool I managed to lose 5 stars but I expected more of a challenge, especially getting from the hospital to the rail tracks.
Anyone else had this problem? Maybe I just mastered minded the escape perfectly
