Total Vehicles that are running on city roads, that uses petrol and diesel as fuel, should not be allowed and prohibited for its use, and instead most efficient and environmentally-friendly electric cars are used.

In the forthcoming, paragraphs I will explain in detail why transport vehicles that use traditional fuels should be forbidden.
