Found this after stumbling across the 'Ask Geoff' thread. He might not like to do interviews, but this is quite a good read - the subject of GP4 modding, forums, and comments about the GP series engine running 'on rails' are all mentioned
It’s always nice for me to understand any of the man’s philosophy, as I am completely addicted to Grand Prix 4. I drove in-game for six seasons in a row full length Grand Prix. If the physics were not so realistic, I would not have bothered. Now I have a new hobby that I am even more interested in.
I think that 'Grand Prix 5 still feels like an unfinished business.' will continue to get hold of some area in the brains of the GP series fans until it will be done - whether it will be in 5 years, or 20 years. Or never.
