I always assumed the game needed more small piles of rubble and things that require a “hacking” style minigame to parkor over successfully. Clothing of various types would increase/decrease chances of itself/other clothing items getting torn, even in a successful attempt. So that long flowing duster is probably going to get caught on rebar, but a skinsuit worn on the outside would decrease chance of anything getting caught.
Additionaly gloves would make sure you don’t scrape up your hands on the rough cement, although small chance for damage to occur even with gloves, it would just damage the cloves instead. This should properly handle “wear and tear”
Also tetanus, including booster shots, and pre shots.
Unfortunately that would also mean that rubble would have to deal damage to Z’s like really crummy traps. I suggest this be fixed with reptillian (lizards and snake) Z’s and reptilian mutation Z’s which, having scales would just slither through the rubble without difficulty and catch you getting stuck on ‘every other’ pile of rubble.
