I agree the cars in GT7 look good, and in a sense cars in FH5 also look better than FM. But again I think those other games are actually unrealistic in that if I look outside at real cars, they don't have strong clear reflections, at least not in the conditions here today (quite bright sun, but a lot of cloud as well). They look a lot more like FM than FH5 or GT7, but I think those games look good to most people because they've intentionally dialled up elements that they've found cause people to think it looks good.
This is ACC (left) vs real life onboard footage (right). The real life footage has so much less contrast and saturation. It also shows another of my pet peeves about driving games, which is interiors being far too dark, partly because of the excessive contrast. I swear people would say it looks bad if someone released a driving game that looks exactly like the real life onboard footage, but that is kind of what has happened with FM.
