I thought about this as well on the couple of times ive played B-spec, and just cant beleive what a missed opportunty it was for a concept thats been pottering around in Kaz's mind since Gt3....
It is far too simplistic to have any real benefit or fun attached to it when some additional complexity could have easily added a whole new dimension to the driver management concept.
Now I am definately no programmer, so I have NO idea how complicated such a game could be.
But thoughts I had were along the lines of directing your driver how to actually improve their racing over say the 10 lap race (which is pretty common for the b-spec races). Instead of just speed up/speed down, have break earlier here, break later here, take shallower line here, accelerate earlier, dont break here etc as the driver is driving. Your commands therefore dictate how the driver attacks the course itself. Using the available telemetry (we know this exists) and comparing it to other cars maybe, you can problem solve the race to get your driver up there with the best and put him into contention, instead of just simply telling him to up the pace without being actively engaged in what your driver and the others are actually doing.
Then there would be addiitonal commands for contextual driving, such as draft car, pass inside, pass outside, keep position etc.
The game suddenly starts to sound quite busy and involving. Micromanagement has made plenty of popular, fun and engaging games.
I for one am hoping they improve the implementation for GT6 as it definately has merit. It just needs some more work.
On a side note, i do have a favourite moment which was during the sport truck race and it was the last lap at Laguna, my Ram coming second behind a very fast Tacoma. Up the hills I kept pressing pace up, pace up, then finally overtake, desparately wanting to win this and not have to repeat it. To my surprise, my Bob tucked that Ram up the inside at the corkscrew in one audacious move that would have made Kobayashi proud, the perfect pass, and went on to win it.
