100% right.
If I lock spool, I should be almost constantly drifting and it should be manageable - but it isn't. Currently only 4x4 cars are drifitng well (and stock Aston Martin DB11 as RWD exception). This indicates there is a gap in physics that cannot handle drift.
And if a game will be capable of drifting, there should be a separate competition for this. I will definitely drift as from time to time this brings a lot of fresh fun. That said, drift in AC or GT Sport wasn't for me, but drift in NFS Shift 2 ohhhh men it was such fun to catch those perfect lines! And with PC being a spiritual successor of Shift 2, I would expect something similar.
