I'm not 100% satisfied with it, but given the level of physics realism the steering is tasked with translating to an analog stick (as highlighted in
@slthree's post above), I'd say PCARS3's implementation is better than most games across the genre, really. SMS deserves commending for it.
Of course, the problem is SMS's decision to hide any parameters to adjust the steering or choose options like you could in PCARS2. Right?
Regardless if it's all new code, surely there are variables that could be adjusted and features that could be disabled, like damping strength, an option for linear 1:1 axis control (some people like it), or the behavior that resembles the "Opposite Lock Help" available (optionally) in PCARS2. It's not too late for a patch, if we can expect anything like how PCARS2 evolved after launch.
My decision to purchase any DLC is kind of hanging on whether they patch in some options we used to have in PCARS2, from graphics effects, to the camera, to controls. That's my primary (realistic) expectation.
