This was a frustration I had from early on as a PCars member (I bought in about as early as you could, so 2-3 years before the actual game release?).
It was obvious from our view that SMS was aiming for the stars...and we'd probably get to the outer atmosphere. To be fair it was nice to see such enthusiasm. There were plans for yellow flags, safety cars, full pits, ovals, etc. I'd say they delivered on about 85% of what was brought up in various threads/posts etc.
If I'm personally honest, I never ran into Ian Bell on the forums - but it does seem like he's a bit of an asshat.
I mostly feel bad for people who bought in as NASCAR/Indy fans as that experience is definitely being nerfed. To me that's a big pile of crap. I wasn't one of these, but I think that was their biggest cock-up. There is a small part of me who thinks they will fix it and release it at some point.
I'm really sad to see the PS4 and XBone versions to be so cruddy even after patches. The PC version is pretty solid (at least in my gaming group, a small group of five). We don't get crashes, issues, landmines etc. We're either very fortunate or the PC build is solid now.
I do hope that a lot of these promises show up in PCars2. I haven't seen enough on that forum to decide.
Have I gotten my money out of PCars? Hell yes. I already bought into PCars2 (admittedly before things went all sour with more and more dropped promises and questionable DLC future...). It's the best racing game I own/have played and I do enjoy it immensely when running with my buddies.
I think, having been inside prior to release, I just knew we were coming up short on certain areas...so I guess it wasn't as big of a shock to me. Still enjoy the game immensely, but I do miss full pits and I desperately wanted safety cars...
