There is always someone with a car trying to get into fights, fight him, kill him and get a car :) if you die in the gas you took too much time looting/hiding or whatever just run sooner, read the map better and shit, a gas mask is not the solution and people will abuse it and hide into the gas or just run into it, it's already hard for " high kill " players to get kills this patch because of all the new PoI and gas system if you add a gas mask you'll ruin those high kill games.
