...Amen. So true it hurts, this quote. Personally, I can't understand the reasoning behind this strange insistence by PDI at all. But they have stuck to it until now, so it's hard to see them change for the next game.
As for strapping a big turbo on race cars, I'd say as long as grinding remains a part of the single player experience, I want it to stay as is - back in GT5 (and in GT6 whenever I don't wanna drag RB fan cars around) I'd take a race mod ZR1 Corvette with a supercharger bolted on, and grinded credits like a dazed teen high on
something watching a hundredth repeat of an Attenborough special.
Without the said boost in power, the monotony would've lasted a bit longer, you know.
