ELI5: Why did 'SOLAR FREAKING ROADWAYS' never come into fruition?

For something that seemed to make so much sense/generate a lot of hype, why has the idea died off?

The people making it can't even figure out how to get a roughly 15 foot area of sidewalk panels to light up, let alone produce energy, and that's after several million dollars, and YEARS of work.

The entire designed is flawed, as they are too fragile, would never be able to reach 100 capacity (solar panels need to be angled towards the sun, road needs to be flat).

Plus, glass is a HORRIBLE road surface. Aside from the fragility issue, the second it rains, you'd might as well be driving on ice it's be so slippery.

Oh, and it's also completely cost ineffective.
