That depends. I will be putting gauges in my car some point here in the near future just because I want to be able to look with out really looking and see that everything is alright. Yes, I could look at the dashdaq for but you really have to look at it versus just see the gauges out of the corner of your eye. Kinda like coolant and oil pressure gauges. I never really look at them but I can tell you the second they're not where they're supposed to be, I notice it.
