Plot hole: After Kate's successful escape, it should not be too hard to find the killer's lair: she ran (probably in a fairly straight line) for a few minutes only from a cave-type structure to a 5-10 metre waterfall. How many waterfalls (possibly with caves or structures nearby) are mapped in that forest?
Character mistake: Casanova refers to Cross's gun as a "Glock," but it is a Sig.
Answer: Shooting out of the tires on a fleeing vehicle is not a viable, realistic strategy. It is a movie cliche akin to shooting out a padlock or saving a hanging man by shooting the rope. It is not something people do in real life and it is therefore realistic that Morgan Freeman wouldn't attempt to do so in this film.
