It really is a shame they ran into these issues, as the game is solid as an arcade racer. Me and my club members are having a blast with it and when the online portions work, the game gets even better.
I hope they get another opportunity to relaunch it as the game really deserves a second chance.
As for the Ps+ gamers who have to wait, I feel bad for them and I was one if them, but I took the plunge anyway and got it and I'm one of the many that doesn't regret it. The sense of speed along with the crazy amount t of detail, genius track design and perfect balance of arcade and sim make this game highly addictive.
