It quite noticeable on my BMW E39 if you come to a stop with the footbrake applied and keep it like that until the handbrake is applied.
It's because the suspension design has the pivot points other than at right angles to the body. So if the wheels are locked and the body attempts to move, the body goes either up or down slightily. Trailing arm suspension being the most noticeable. Release one pair of brakes and the body settles, so the car moves by a tiny amount.
What is more important? Suspension which grips well and is comfortable? Or a less efficient design which doesn't show your symptoms?
I'd agree with that one. Think it may be made worse by the use of limited power LEDs. The indicators on those cars are never that bright - easy to miss in the sun too.
