It's seems the coolant temperature level around 210 degrees Fahrenheit. Has anyone's spider gone higher than that?

That's one thing I found surprising about the instrument panel, the coolant gauge is essentially useless and might as well be replaced by a warning light, expect that we have one already for high coolant temp (does that come on fabricio27?)

In the Euro versions we have 100-110-120°C, and I imagine that US versions show 210-230-250°F (am I right?). A normal temp will be around 85-90°C (around 185-195°F) and approaching around 100°C (around 210°F) only when really hot, when the radiator fan(s) should be on. I've not checked, is there 1 or 2 fans?).

You will only see any movement on the gauge when it's starting to overheat, it will not tell you for example if the thermostat is failing open and the engine is running cool, say around 70°C (around 160°F) , so in my opinion, the gauge is pretty much useless. I would much rather have a gauge showing 70°C-120°C (160-250°F) and even an oil temperature and pressure gauge would be good as well, it is a "sports car" after all?

I wonder if any of the display is controlled by software? I assume it is the same as the MX5 ND (I'm sure Fiat would never have designed such a useless gauge for themselves?) Perhaps like the Infotainment system, it can be reprogrammed?

There is high coolant warning light, regarding electric fans not sure how many. Maybe next summer in the Las Vegas, Nevada heat of over 45 degrees celsius will see the temperature needle move a little bit!

I don't know about Fiat, but some manufacturers will run their cars much hotter, around 100°C (212°F), because the engine loses less heat and thus is more efficient when the coolant is hotter. About one third of the energy contained in the gasoline used by the engine is lost in heat.

I drove across West Texas in 100 degree heat with AC on doing 80 mph, with the temp gauge comfortable lower than 210 the whole way.

I don't understand why you say it is useless. I would agree that as long as the temp stays in the normal range there is not much to see. But when the temp starts climbing, you may find the information useful. If the used the "useless" space on the dial for some other measurement, say voltage, it would detract from the "oh, sh!t" feeling you will get when the temperature reaches 250.
