I never have this rollback issue but my wife does. Not sure why either, I guess there's allot of automatic transmission driver's that don't drive like I do. I learned on a manual but not sure if that matters.
My old Ford focus with dct (automatic clutch)worked the same way, as well. If you press the brake it will hold otherwise you have to give it some gas to clutch it, since it auto shifts into neutral at a stop to prevent excessive clutch wear.
But even with a manual it's better for your clutch if you hold the brake, so that's just how I learned. lots of reasons to press the brake instead of just relying on a transmission or clutch.
That is why I don't mind creep too, it keeps my foot on the brake where it should be, and allows me to slowly move forward easily like all the other automatic transmission cars. Meaning it's less work than with creep off since your foot should be on the brake anyways.
It's not about automatic vs manual to me I never understood this argument either. If you drive a manual you don't typically push the clutch in and shift into neutral for a short stop, you just clutch in and brake then release the brake and clutch forward then go.
Then again I never had one of them fancy manuals with the anti roll backwards stuff either, maybe that's the part I'm missing?
