Industrial system integration (automation engineer in auto plants.) I wouldn't say I`m knowledgeable. I simply tried to put some thought into how to make the current road tech into "what`s next."
I thought TED`s would generate power during periods away from 50 deg and the electrostriction generated power proportionate to use (big trucks, more flexin`!)
Another point of the thermo-electrics was "feeding more DC current through the road than it generated would warm the surface" but, looking at Thunderf00t`s energy projections for what looked like mica plates, much better heaters than TED`s, heating the road enough to defeat snow in 20-30 deg weather would probably cost more energy than can be stored easily.
All this would depend on being able to secure materials at rates less than just using salt/sand for 10 years.

"...with all the bumps curves and hills in the road how would you be able to make the panels for every single situation without flattening all the road?" You can't. Banked curves would feel like driving a low-res simulator.
breaking the road into tiles seemed like they were trying to lower maintenance. It doesn`t take foundation settling into account: A continuously driven road is constantly sinking, unevenly. Edges would be jutting up all over the place.
Roads are not flat but, arched to drive water to one edged or another so, the tiles would need to match the foundation shape. The tempered glass and foundation would not age similarly. The current surfaces just mimic the foundation shape.

"...mixed system of solar panels and piezo electric generators under the road surface..." In 2011, I had an idea about integrating a Peltier system into the roads, probably combined with electrostriction. -The temp differential generates current. -The continuous compression/decompression/flexing also generates. The idea was to utilize the conditions that break down roads to supplement maintenance cost.
I do not currently see such a thing replacing the primary grid but, it seemed worth investigating to add to the mix while proposing a more durable road construction standard. Someone else was already developing nearly the exact idea.
I think the daylight visibility can be overcome. I just think the current design, as presented in this video, is not good for more than self-powered lane markers and signs.
