Sometimes Mrs Don says that I'm driving too quickly/slowly - that's a subjective assessment, in some cases made when she hasn't even looked at the speedometer. OTOH if she looks at the speedometer and I'm going faster than 70 mph on the motorway then, regardless of my own personal opinion on the matter, I am driving too quickly.
That is still a concept of objective good. There exists a speed that is unacceptable. You may not know what it is or each person with limited knowledge can only guess what it is. That is different from a statement that it should be whatever the majority agrees to.
