Very frequently cars and trucks will just fly off into the air, underground, or just swing wildly around the road killing you while driving or putting parts on. This has been an issue since I started playing the game a year ago. Many people complain about it.
Happens on old gen and series x
Happens with anywhere from 1-32 ppl on server.
Happens on vanilla official and on modded private.
Get in vehicle and drive, it flips out and you die.
Try to put part on vehicle, it flips out and you die.
Would be more than happy to compile video evidence and/or any other relevant information you require to assist with this issue.
Afaik the main reason for suicide cars is the server performance.
The server side of DayZ is poorly optimized and high player count servers can't keep healthy and stable fps when high/full pop :/
Yeah the last time i was on a full pop livonia server we barely touched a tree and 4 of us went flying and died on spot.
I wish cars was driven client side so when YOU the driver is trying to go somewhere the game is not positioning you where the server THINKS you are [inteprolation?] considering 40% of my wrecks are the server repositioning me where i know im not - like a sudden shift to the right when i was going straight for a mile.
A poor physical implementation can be another reason for this but trust me it's mostly related to poor server performance (and maybe Netcode).
