I keep having the same issue while driving on xbox, I can get the full speed out of any car I have driven, not long after I do this the game shuts down I though it was because my xbox is a MK1 but I have others play with me on my nitrado server who have an xbox 1 x and suffer the same issues between the 8 of us that play like losing cars and survivors it's very frustrating when you're miles away from your base and the game crashes losing my car, the inventory bug is so annoying too if I switch anything in my inventory for something else in a container it will not let me take the swapped item out until server reset
