NOTE*

For cost:

#given that an average car can contain 45-65 litres, we estimated an average of 55 litres fuel efficiency per car.
#choosing the Esso gas station as our target fuel provider, we calculated cost based on their current gas prices of $1.09/litre.
#in order to receive the final cost, we assumed that per every 1 km driven, 0.5 litres of fuel was consumed.
