Several of us began discussing some ideas for how Gran Turismo could expand, and an idea that a few of us came up with independently was the concept for a whole new mode of play, where you race in a career. This doesn't have to affect the typica GT game of the past, as it can work alongside Arcade and Gran Turismo mode, and you can choose to participate in it or not.
Career Mode in my vision of it would take you as a hobbyist driver with a car that you bought and modified with a basic starting budget, entering races in something like the SCCA, an enthusiast non-professional league, but organized much like the enthusiast leagues around the world. There would be a calendar, scheduled races, a roster of drivers with individually coded AI and racing skills/traits, weather, time of day, seasons, the whole reality thing. Wins in the enthusiast circuits gets you some prize money and recognition, which translates into a selection of sponsors willing to back you and fund your racing activities. So just as in GT Mode you race for money and prize cars, you race in Career Mode for prize money and sponsors. Better racing gets you better sponsors with a bigger racing budget and bonuses. And there would HAVE to be a paint shop to give you your own personalized paint scheme and car number. Polyphony could provide a library of paint jobs to choose from, and should be able to provide us a certain level of customization, or even give us something like a basic Photoshop to allow us to design our own from scratch or templates.
Winning the championship of the enthusiast/semi-pro league provides a springboard into the world of pro racing, where a team either hires you or you take your budget and sponsors and create a team of your own, with cars, garage and team of mechanics and engineers. And you choose a career in a class of racing, like Rally, Touring Car, (CART) or Formula 1. NASCAR, what's that?
And you would carry on like before, participating in the race calendar for that year, trying your best to win races or place near the top, to win the championship of your chosen field. Trying to sign contracts with prime big budget sponsors would add a nice touch. But it doesn't have to stop after a year. You should be able to keep racing until you decide to quit, racking up championships at the end of every year. Or you could switch careers and go to another class of racing. With downloadable content like new cars and tracks, you wouldn't be faced with the same old tracks and same old races every year. Or racers, as Polyphony could also provide a new crop of racers with their uniquely coded AI, giving us a completely new racing experience when we want to spice up the variety. I have a feeling that I'd want revenge on a few virtual rivals though.
Along with that, if you wouldn't want to start at the very bottom but get right into a year's worth of racing, there could be Season Mode, where you pick a career and start with a car and team and race for a season for the championship.
But my dream is to see some version of Career Mode in GT5. I've been trying to "evangelize" this to people, and so far everyone loves the idea, except for the people here who don't want to mess with the established GT formula. But I agree that GT should expand to encompass every aspect of racing, including doing what real life race car drivers do, and turn it into a lifelong adventure.

It could be a possibility right?
