I had a real pain in the ass before. As soon as the mission started I jumped into my Sultan and headed towards the rear of the car park like I always do. I jump out and as I'm running to the wall this guy runs me down with his Adder. At first I think it's a mistake, but then he runs me down three or four times and intentionally kills me (I cannot get to my feet to do anything about it.).
While he's doing that one of the other players tries to solo the entire garage on his own and takes up the only team life, so I'm stuck in spectator mode. I then watch as this guy runs down the remaining two members of the team and kills them as well. He tries to solo the rest of the mission, and in fairness to him he did a half-decent job until he tried to sticky-bomb a pursuing SUV and ends up blowing himself up in the process.
What makes it even more moronic is that this guy was the host - if he wanted to do this solo he could easily have done so.
