Agreed, they should have a colored scale from:
red -- poor -- 0%
yellow -- ok -- 5%
green -- fine -- 10%
blue -- great -- 15%
gold -- superb -- 20%
Attach a tip % to each (perhaps)

Only one driver though, provided me with water bottles and candy. That was a superb experience. Maybe the only superb one while the rest were fine.
