That would be quite hilarious actually. especially after the tornado ripped up all the solar road panels forcing us to repurpose the fans back to making wind energy again.... which would have been really effective during that tornado it created.
I was also driving around just the other day and started thinking about the smart solar roads and how they could change our everyday life should it ever become a reality.
I was thinking about how people use their GPS and have to look away from the road to see the screen, and how people are always speeding, driving crazy and running lights.
If every car had a GPS and/or identifier, it would prompt you to slow down when driving way too fast, and encourage you to keep a safe distance to the car in front of you by displaying your selected route on the road in front of you.
ie. You car says "In 300 feet, make a right on Center Avenue" and on the road in front of you right turn arrow lights up pointing at Center Avenue. "Your Destination is on the left" and a green arrow appears infront of the place you were looking for.
I realize that me be confusing if there are other drivers on the road, but it should literally be right infront of your car like a Sims Marker above it's head.
Of course the downside to this is that the road will now when you've run stop signs, red lights or are generally speeding beyond safe driving levels and can either ticket you automatically or alert authorities who will then take it from there. Kinda turns the roads into a police state situation, but they will be safer all around. remote activated auto-pilots... that pull your car over and park? I dunno...
another one that comes to mind is real-time traffic with smart GPS rerouting. The road can detour traffic to prevent major congestion on any one specific road. Lots of times there are plenty of routes to get to where you are going, but most people don't know the sides roads and therefore just cause more traffic by becoming part of it.
The more I think about it, the more this seems like something Google would want to be a part of.
