if you buy a brand new car and the engine stops working after 1 day wouldnt you be upset and want to get it fixed or replaced asap? i know as soon as ANY of you encounter the problems i have you will say exactly what i am.
To take your car anology a step further, say you did buy a new car and it developed a serious rod knock on day 1. You bring it in. The techs start working on it. Then you start screaming in the lobby because they can't overhaul an engine in 10 minutes flat. So, they have to pull the mechanic off the job every few minutes to attempt to convince you that it is being worked on, all while not actually working on it because he keeps getting summoned to the lobby. Someone else, we'll say me, comes in with their engine just as dead as yours. They let the desk know, then quietly sit in the corner and watch Youtube videos on their phone. In and out, two hours flat.
Constantly screaming and moaning about the bugs in NV is only going to slow the patch down if it does anything at all. Mention it once, politely, then just let them do their job. They'll get the patch out faster. That PC savegame bug hit me, my autosaves didn't work. I didn't whine about it, I just made manual saves and they eventually patched a workaround in that fixed the problem.
Patience, friend. It's something you need when dealing with something that's broken, and a lack of it is why many people don't like working in public service jobs of some sort.
