i actually think the tracks in lfs are quite poor in general. this is not to say they aren't fun, but they are just too easy, and after you've learned a track and developed a good set for it, it becomes a boring routine of throttle, brake, turn, repeat.
the difference between the tracks in lfs and real life tracks is not necisarily the number of braking zones, but the number of complex sections where you are neither braking nor accelerating, but working like mad to keep the car balanced. as much as we all hate GTR, i've been playing it again lately, and almost every corner is difficult in it's own unique way.
