No they use slow reacting gauges because most car owners are stupid. The first gen miata had a real oil pressure gauge. Then in 95 they changed to an idiot gauge because too many owners began questioning why the gauge was "fluctuating".

Miata owner?
Well I thank you all for pointing out the specifics of the operation of the cooling system. Now knowing that this engine among most motorcycle engines is built to run hot, or at least be able to, and that the thermostat starts opening at a very low temperature while the fan cuts on at around 212*, I still have to ponder why such an extensive range of operating temperatures is allowed. It's certainly not optimal. But maybe it was just more expense than it was worth because obviously, like stated before, the engine does perform and hold up well. It really just sacrifices cold weather fuel efficiency. Oh well. It's not a big deal, just curious.
But the real situation is probably just what drymartini just mentioned: I'm just stupid and it's showing now that I'm driving a vehicle that has a real temperature gauge rather than a graduated/slow reacting one!
