Drive on Solar Panels?

Questions of durability and cost effectiveness still need to be answered, but this is certainly innovative thinking. The public already owns the roads, so they can be paved with whatever we're prepared to pay for. Roads usually go places where energy is used, so there is a certain synergy here.

On the other hand, the public owns an awful lot of rooftops, and they could be covered with solar panels that don't need to be as durable as these.

Crushed glass has proven to be a pretty good aggregate substitute in asphalt roads, so the concern hinted at below has probably already been addressed.

Solar Roadways certainly deserves a chance to make their case.

Solar Panels Built Into Roads Could Be the Future of Energy | Popular Science:
"The Department of Energy just gave $100,000 to upstart company Solar Roadways, to develop 12-by-12-foot solar panels, dubbed 'Solar Roads,' that can be embedded into roads, pumping power into the grid. The panels may also feature LED road warnings and built-in heating elements that could prevent roads from freezing.

. . .
In addition, every Solar Road panel has its own microprocessor and energy management system, so if one gives out, the rest are not borked. Materials-wise, the top layer is described as translucent and high-strength. Inhabitat says it's glass, which seems odd, especially since Solar Roadways claims the surface provides excellent traction. The base layer under the solar panel routes the power, as well as data utilities (TV, phone, Internet) to homes and power companies."
