> ... using solar panel road surfaces, with excess charge stored in giant capacitors and used to heat the road surface... Ouch for anyone with rudimentary EE knowledge. Perhaps with kilometer-thick capacitors under the road... they by far don't have the capacity to do this. And staying on road with snow-covered markings will be likely solved by relying on GPS, if it's not already.
