In before you say, well he is Batman so he doesn't need a chute, umm he kind of does. Nolan tried to ground Batman into realism with every aspect and for a character such as Batman, who has no super powers besides his unyielding will and piles of money, he should be a victim of physics or at least trying to use it in his favor. Now before you say that Batman usually swoops down on his prey so the force of the impact goes into them, then you are pretty much saying that Batman kills these men and women. The speed that Batman is going when flying the wingsuit is roughly 70 mph(110 kmh). If he used the criminals faces as make shift shock absorbers, then we should add how many Newtons that is.
Batman has the mass of 95 kg. If Batman is moving at the velocity 110 kmh, then we could factor in his acceleration as well.
I would factor in the acceleration, but assuming that gravity will forever be a bitch and constant at 9.81 m/s squared and he needs at most 100 meters(328 feet) to have any sort of lift so he is going pretty damn fast and probably would still be going to fast for him to land safely. You guys could come up with acceleration if you want.
Toughness of the suit? Armor does not work that way where it can absorb impact from falls.
If I have anything wrong, please correct me.
