I prefer actual gauges in my vehicles but recent events may have proven to me that idiot lights are actually superior. Person gets in my truck, looks at the dash and ask what all the gauges are for an then starts to drive. With this question the thought crosses my mind, 'What good are the gauges if the drive does not know how to read them?' Now knowing this and also knowing how many people panic when a check engine light goes on it it better to have the mystery light illuminate brightly or a gauge that is always there that they ignore since it means nothing to them? They at least might ask about the light since it is new on the dash. This said some just don't care till the car starts smoking regardless of what the dash says.
Just a thought.
