i've noticed mine hugs the right more than i'd prefer. not all the time though.
what i don't like about lane centering or whatever you want to call it is the pressure requirement on the wheel. it seems to want some sort of death grip on the wheel to remain active. kind of counter intuitive to its purpose if you ask me. I normally just use lane keep with nudge turned on so if i do get distracted on a long drive and drift, it'll keep me in the lane.
also, please note these systems will always allow the driver to override their input. so if it even has the slightest input that you've moved the wheel, it will release control. which goes back to my gripe about needing a death grip to stay active. i just don't use it.
