The future inside of ten years will see self driving cars using no gasoline or a heavy engine either and having a modest battery. We will also all have them and the cost involved in transport will plummet. This revolution will liberate millions of workers from transportation who are all capable and will flow naturally into supplying the needs of a population no longer needing to spend heavily on transport.
It will be different but also richer. After that we will have the grav float that takes the place of the car and that will be also self driving. After all none of us have eyes in the back of our heads..
Better yet i expect self driving airships dominating long haul transport to show up as well. Grav floats will do that also but may be just too costly while an airship not needing a professional operations crew can become very cost effective.
