if petrol was in short supply then emergancy services would be the vehicle that needed it most eg the police, ambulance and fire brigade
It depends on the cost of said petrol and the efficiency of the vehicle in "miles per unit of petrol". You didn't supply enough information.
It is likely that the world's petrol supply will run out. There are limited resources and if people keep using them up, without thoughts of conservation they could very well run out.

yes
The petrol combusts (burns) so it bursts into flames. So cO2 and heat are released. An example is in cars. In cars incomplete combustion occurs, this is when there is a limited supply of air available so no damage is done to the car.
Your question is confusing. Are you asking why the governor is not working or are you asking why is there not a governor on a petrol engine. Modern fuel injected engines are governed by the ECU which will shut off the fuel supply when the vehicle reaches a predetermined speed. Some older vehicle with a carburetor had a mechanical governor but most had no governor at all.
Supply, demand & competition.
A limited supply.
The engine will not run without a supply of petrol so you would think it is useful.
