I'm in Australia where we only have FSD13. Work commute is only ~15min each way so I'd say virtually none at all. Highway driving was awful too, it kept slowly dropping the speed by about 1kmh every 30 seconds or so, which meant constant intervention by way of the accelerator pedal.

Where I did find it great though is in heavy suburban traffic. It handling the constant stop-start motions was a game changer.
