It's a movie. It's not going to be 100% realistic. That being said... He's wearing a suit that is designed to absorb and dissipate kinetic energy. It makes sense that it would help dissipate the kinetic energy of landing on concrete and getting hit by cars. If you paid attention you noticed that after these impacts, he was significantly slower as a result of the injuries, and was less capable after than he was before. By the final showdown, he's literally struggling to stand, multiple bones are bruised or broken, and he keeps going by sheer force of will. He is wolverine in JW4. Literally, no, if you saw the movie all the way to the end. (Spoiler alert: JW dies from his accumulated injuries.)
