That's reasonable, but it should be something specific for blocking that requires much more complex crafting. Fireplaces are extremely simple to make, are near impossible to see, and stop a car dead like a thick tree. That is an absurdity. The fireplaces are a nightmare on the community servers as it renders car spawns either useless (fireplaces places under spawn) or roads constantly full of invisible death traps for places. On official it's irrelevant as sadly only ever seen one driving car in all my years of playing DayZ on official across numerous platforms, thousands of hours. That's telling in itself that the vehicles are too hard to put together on official, a whole other topic, I've met players who didn't even know drivable cars were on it, and that they are actually quite fun to drive with decent physics for players in PC or Series S/X or PS5, which is most players now.

This is a huge new issue on high population servers.
