Hey did you know if you look down holding the binoculars and jump you can glitch jump to high areas but be careful not to hit the binoculars on a ledge and/drop it it's devastating damage
One last thing, sometimes when you have the advanced weather mod and there is lightning, it can strike the mutants and kill them. They are charred afterwards. I don't know how rare it is, but it's happened twice in my playthrough.
Also, I noticed if you press q and scroll down in your car, you can hide in your seat. This is handy if a mutant is outside a stop, that way you can drive past them and they won't notice. You can also crouch all the way down outside, and they won't usually notice you unless if you run into them.
