why don't you create a slot in the inventory where you can save it from beeng looted or stolen,and to apear when you respawn,this shoud resolve this problem:
[...] but to make cars more safe. I mean everybody can steal your keys or simply kill you and loot them. I believe they should be harder to get so its safer for people to ride around in cars. Everybody is afraid of loosing them and that makes them absolutely useless feature. I believe that almost no one is using cars right now. Only some brahmin caravans maybe and then some buggy since they are cheap but thats it.
so players can safe an item when they respawn,like a key,ar a wepon or a brotherhood armor they buyed,not made(i mean 15kcaps for 1,anl lose them in favor of a PK whit rocket launcer,is sucks)
but,to make it unabuzeble,you can stire 1 item,not 1 slack of item(like ammo and resourses)i know it sucks,but PKs must make a living too(i am not PK)so you can't store 4 HQ iron ore in a mine,only 1,and not be able to save 4500 caps you lost to a random encounter,and to use it ,you must put it back in inventory,like you have 150 caps,you put 1 cap in the safe slot and in dialog to apear 149 caps
this whoud increas game dificulty and make more fun(you found accidentaly a super slege,and get PKd)
well,now i sugest only for keys
what? Radios? You dont like to waste junk to craft it? car keys and thats all
