I am working on my thoughts from a purely speculative perspective. The best vehicle that could leave almost 0 footprints are what I am calling (S/EVAH), The vehicles just like Stars Wars but Autonomous as well.
The third wheel for complete vehicle dependence from Homo-sapiens, who are prone to accidents are (S/EVAH) Hovering Cars,
in the spirit of either Maglev train or yet to be invented technology.
Benefits of Solar/Electrical Vehicles – Autonomous & Hovering(S/EVAH)
- Hovering: Independence from Terrain, from Deserts to Rivers, rough terrain, open terrain or no terrain.
- Hovering: Rain, Sun, or Snow, always Jam-less Traffic.
- Hovering: roads replaced with electrical rods for hovering vehicles, giving more space back to earth.
- Hovering: Increased predictability of traffic, reduction in accidents, and arrive on time always.
- Autonomous: Monolithic travel turned into social hub by communicating with other travelers.
- Autonomous: collectively millions of morning hours saved daily & speeding up human productivity.
- Electrical/Solar: Independence or limited dependence from resources of Earth.
- Universal: Built on Earth, can be driven on Mars.
Big Perceived Challenges
- Human Ego, Patriotism over Love of Earth, Lack of collective Human will all over the planet to work together.
- Lack of Hovering Experimentation Data
- Thunder and Electrical may short vehicles electrical system
- Better methods of harnessing Solar energy for longer travels.
- The backlash from established businesses in the vehicle and associated industry.
