Cars will be replaced with mini family-sized planes that will be owned, manufactured and sold by airlines currently in existence.
As pollution levels rise and the world’s population grows the only solution to congested roads will be in having no roads at all. Planes will be sold for the prices of cars and the roads we have now will be subdivided and sold off to builders and individuals.
A huge distinction will be made between where humans live and where they travel with all travel being done in the sky – the airways.
Without the need for roads and freeways people will have more places to live and more room to spread out, thus alleviating all issues associated with pollution and congestion.
