The demo video touts them as "eco-friendly", and I'm assuming they mean relative to traditional pneumatic tires, so how are they actually better in that regard?

What exactly do you consider freeway speeds? Even in the metro ATL area which is notorious for thinking the speed limit is a suggestion, the vast majority of traffic is moving under 85 MPH.
Inb4 congress tries to pass a law prohibiting them because they can be used by villains to defeat LEO's spike strips.
Wouldn't run-flat tires then already be banned?
The casing would still fail catastrophically at high speeds (i.e. pursuit scenario), and having a tire down over 30psi on one wheel would very seriously affect handling at any significant speed (40mph or more).

Would love to see a bicycle tire with this. Way too many glass pieces on bike lanes :-(
I think the best solution is to use pneumatic tires with a Kevlar liner built into the tire casting.

I am pretty happy with my run flat tires on my bmw, even after a blowout they remain normal and handling is near normal as well, plus you can drive like 100miles and 50mph to a nearest tire shop. The only downside is they are more expensive and sometimes if you cought nail close to a tire sidewall it means you I'll have to replace a tire since it's not fixable
And they ride more harshly, are less compliant, are heavier (look at how much some spend on light-weight rims; tires are even further from the center of the wheel), more expensive, can get bent / dented, and rely on finicky tire pressure monitoring systems.

A 3D printer could be used to create the mold for the rubber perhaps.
You can easily do a lost-wax process with a 3D printer. (Although getting the precision may be difficult.)
