Agreed. Other than being extremely annoying, it also affects the game negatively. I had a situation where four people were trying to get the unique car for Simeon, and right outside of the garage it all went to sh*t. Because as soon as someone killed someone else to steal the car, another person would have spawned back in and run over to kill that person, and when they get in the car the original owner was there to take it back, and the cops showed up, and no one could do anything.
It was just an endless cycle of pointless killing and dying, no one was given enough time to actually deliver the vehicle. I died twice and gave up. The amount of money I'd lose trying to get the car wouldn't even be enough to cover my losses, so there wasn't any point in even trying.
I had this exact scenario a few days ago. It was actually me who go the car first, it changed hands around 3 or 4 times, and fortunately I managed to deliver it. But I ended up losing money because of all the dying!
