Solar roadways failed for the same reason Tesla will NEVER outsell gasoline cars: bad technology that's orders of magnitude worse than existing solutions. That being said, a huge leap forward in technology would make BOTH viable. A better road-based electricity generation plan would have been to use piezoelectric panels instead of photovoltaic ones.
