I've only done this a few times, and only when other things were also wrong (excessive backseat driving, made me wait near the 5 minute mark, food stops, etc).
A secret system is actually ideal, considering drivers don't get to see exactly who rated what.
Also, don't promise tips. Everyone knows that's a lie.
