That's one possible interpretation, mine would be that people will always speed slightly above the posted limit because they know the odds of being ticketed are small (up to some very high speed, at which point many vehicles and/or drivers would fail). By setting them lower we are basically playing with two variables - high speed (which means getting people and goods places faster) and high risk (of higher energy collisions with less time to react). Pushing either to their limit doesn't seem like a good idea...

Then drive around America more often. Pretty much wherever you go, whatever the highway sign posts, people go 75-85. That includes places where the speed limit is 55 and where it is 80.

The federal limit of 55 mph was set by Nixon during the gasoline shortages due to OPEC supply control. Clinton repealed it, so some states went up to 70 mph. Today we might consider enforcing them to help reduce carbon consumption (and collision fatalities).
Heck, maybe it's time to go back to 55 as a federal limit. Last I checked, most vehicles on the road get dramatically better gas mileage at 55. Rather, it gets exponentially worse as speeds increase past 60ish due to wind resistance.

That data was true back then, but is it true now? This is a legitimate question. Cars have changed a lot since then. They're mostly plastic, more aerodynamic, and engines are more efficient. So is 55 still the average optimal?

That would tend to fit with my upper limit idea - most people aren't capable of handling their vehicles much faster than that (or reacting to other vehicles doing unexpected things). Of course, when I do drive I'm often stuck in heavy traffic which is far slower than that, so it's more of thought experiment. That said, I'd personally be surprised if people would risk a citation for reckless driving to go 85mph in a 55mph zone.

Indeed. I believe there is an upper limit of comfort for most people (somewhere in the 80-85 mph) and if the limits were raised to 80mph and then enforced at that using automated methods I would support it.

If we charge companies for polluting, it's reasonable to charge individuals for consuming carbon at an unnecessarily high rate. I'd support automatic fees enforced as drivers hit 65, 75, etc. No limit, per se, just trying to internalize the externalities.
Hard limits are strange for things that are continuous and probabilistic. If we could set an automatic fee equivalent to the cost of increased risks, pollution, etc., it'd be a function of speed. Someday we'll have the technology to communicate that back to the driver as they change speed and location from urban to rural, go through construction zones, etc.
Of course, setting an appropriate gasoline tax, paid at the pump, would reduce the value of those fees.

So if i have a solar charged Tesla, i can drive as fast as i can?

I suppose the fee would correspond to increased risk, so it'd be cheaper than for someone who was driving a gas guzzler at the same speed. In the ideal (dystopia or utopia?) world, the fee would also take into consideration average rates of collision by vehicle type, perhaps your age, number of hours spent on the road that year, etc.

We already have a solution deployed: gas taxes.

They're not high enough. And while there are gasoline taxes at the pump, there are various subsidies on the extraction and refining part of the supply chain. I'm not sure the taxes cover the subsidies. It's a wealth transfer from consumers (the ones buying gas) to the producers (the ones receiving subsidy)

Data doesn't back you up. In places where they have raised the speed limit, the overall flow speed does not increase correspondingly.
People drive at the speed they deem safe irrespective of the speed limit.
