This took some absolutely crazy dedication & willpower, but I didn't have a single race in GT4 until I'd got gold on every licence and coffee break, and then completed all the missions! It's the first GT I've played with a wheel & pedals, so I figured it would be the perfect way to get me used to using them. Didn't have too much time to play, so about the 1st month of owning GT4 was spent on this!
Have a saved copy of the game with around 166 days elapsed, all gold & all missions completed. 👍
I'm now trying to complete the game using as many different stock cars as possible e.g. Professional Hall : Race of Turbo Sports I have 5 200pt races in 5 different stock rides.

I'm A-speccing the lot too!
Bronzing licences is agreeably very easy compared to older GT games, but I think they expected this game to hit a bigger market than ever before, and not everyone is as dedicated a racer as some of the big names here at GT Planet.
Hence, for folks that would get frustrated if they can't progress in the game because they can't obtain the licences, PD put in 3 things, easy bronze times & prize cars for bronze times, and B-spec so you don't actually have to get a licence at all, and is an easy way to make tons of cash to tune cars to ridiculous levels so races become a formality.
This keeps everyone happy. Gamers can rush through the game, hit 100% without much difficulty, other than having to do the missions, put it on their completed list and move on to the next game. For us true GT fanatics, there's plenty of challenges and possibilities. PD have pretty much covered all bases, which was a very shrewd move.
