GT PSP wasn't "rushed" - It's was in development for 5 years.

A game can be in development for five years and still be rushed.

If they miss deadlines,  or things take longer than planned no matter what the dev cycle is a game can be rushes.

Those above three things happen all the time and there are even more things that could happen. I'm not saying the game was rushed, I actually know nothing about it, I'm just saying that just because the game was in development for 5 years doesn't mean it couldn't be rushed.

I seriously doubt a 1st party developer would make any of these errors with an old franchise on 10 year old technology.

What's more likely is that GT PSP was shelved in favour of priority projects such as GT5:P & GT5 , or it's possible that the developement of GT PSP was a lower priority project which occured during the development of GT5:P & GT5 with small resources.

what's certain is that GT psp was not in full scale development for 5 years.
