I love b-spec, which is something I never expected. I never b-spected. anyways. I can only drive a-spec for about an hour, so I turned to b-spec and it reminds me of playing something like Final Fantasy; you have your characters, you take them to different situations, you battle various opponents. Quite awesome.
I started out with C.Chung (Connie) and she's slightly warm temperament. I found early I had to max her cars and keep telling her to calm down. She would always trend toward very hot, and make mistakes. But now that she's around level 9 I can run her hot almost the whole race and she's fine. After I noticed that my drivers will overtake on their own, I realized pushing them on straights and slowing them down for turns can be effective. Listen to the engine, if you don't push them on the straights, it's like they don't mash the pedal all the way. You just have to be careful when curves come. And it does seem like 'pace' is what they try to stay at, once you've set it. So if you've set 'up the pace' like, 5 times, your driver is at 5x nominal, which can be fine if they're experienced, but if you see them making mistakes you can remember that 2x down takes them lower, where they will stay (still +3x) until you issue another order. If my drivers get in front, if I don't monitor them, they seem to get lazy, doing laps in a comfortable way but other cars will catch up. I find it helpful to watch the lap time and see if I can beat the previous, but you have to be careful and not risk too much when you're ahead, just to beat a previous lap time.
My other driver, C.Hill (Chill, the guy from Norway) who is slightly cool in temperament, right away, he was shown to have much better passing technique than Connie, who insists on trying to pass on the outside! She's getting better, but I think I taught her bad habits-- her arrow was orange and pointing downard for a long time-- I thought she needed a rest, but earlier comments show that I probably was teaching her bad (rather than mad) skillz.
Both drivers have won about 75% and lost about 25%. Something I have found helpful-- as soon as I lose a race I look to see what car won. I remember this from GT4; use that car and mod it slightly, and you'll win. The only mods I do cost less than $2000: computer chip $1000, sports air filter $250, sports catalytic converter $500. Works for regular driving too.
I also seem to win better cars in b-spec. I really like b-spec and have put in about 2 days straight, something I could never do with a-spec. I think the designers put a lot of thought into it and want people to experience the depth on offer here (it's like Pokemons, let me show you them). I'm glad for someone like me they've implemented it and I really have had fun learning how and when to issue commands and build my drivers, and it's a great way to acquire cars in the game without having to drive so much myself. I also have a lot of fun changing the view to that of the driver and watching how they break and corner, particularly in mid-engine cars which I completely suck at.
