10 Improvements for Highways

1. High Speed Internet along the highway
• This will happen someday, because as we see now how cities are getting covered with wifi, I guess highways will be next
• It could be profitable if you charge for it and offer plans
• Also, I am talking about wi-fi not 4G LTE and such 
2. Solar panels on highways or ditches
• It would be a good use of highway if solar cells could be built inside
• Ditches would be easier as you just set them up
• It might be ugly, but it would be a good use of mostly unused land
• The other plus here is that highways are usually close to powerlines
3. Build in Rails as an optional form to travel
• This will be if people build wheels for rails in their vehicles
• I do not know if this is more efficient than the current system. If we ever get room temperature superconductors we could build a system so that cars propel themselves forward using extremely high currents, through the rails, interacting with the earth's magnetic field. That would be more efficient than the current system.
• If humanity accomplishes building a system like this vehicles would move practically for free
• This link goes to a webpage that explains the phenomenon better http://hyperphysics.phy-astr.gsu.edu/hbase/magnetic/forwir2.html
4. Build charging stations every 100km
• This would make driving electric cars a feasible option for people living in rural areas
5. Have robots patrol ditches
• Some drones would good as well
• This is to find individuals who have crashed in the ditch and need help
• The drone or robot would alert help when they detect a vehicle in distress
6. Have self-serve food things
• these would have to be durable 
• They would give basic food like granola bars and maybe coffee
7. Have info about attractions broadcasted to phones
• I do not know what type of communication would be good for this, but I imagine museums and such just broadcasting their presence to people
8. Make stories from cardboard cutouts
• This would be good entertainment for long drives
• It would be like those Christmas stories with chocolates that kids get at Christmas
9. Make side rails with advertisements
• It might make the highway safer, and it would pay for itself
10. Have a hitchhiker pick up app
• This way the hitchhiker could see who is picking them up and the person picking them up could see who the hitchhiker is
