I’ve had a handful of experiences where I’m driving a vehicle and something hits me and the vehicle decides to fling across the map. I’ve had this happen to me in Halo 3 and Halo 5.
To name a few:
Having masses of Warzone firefight AI’s walk right past me
Getting stuck in some walls
having a team mate run over a plasma grenade and getting stuck by it
people escaping assassinations by lagging to another location
Some frustrating and some plain funny to watch.
