Are Solar Freakin Roadways feasible?, or just pie-in-the-sky bullshit?

Dave Jones of EEVblog, electronics expert, environmentalist and supporter of solar powered projects debunks the Solar Roadways project that generated over $2.1M on Indiegogo, as well as almost another million dollars in US government funding.
In his video Dave does the solar generation calculations to see if this system is viable from an energy generation viewpoint, and also how much power the LED's might typically consume.
What are the losses in a typical practical system like this?
This debunking covers only a couple of the likely dozens of major technical issues with this concept.
