About buy a car

Recently,more and more people buy cars.
It is very convenient for people lives to buy a car.Especially when one has a baby.
I wonder buy a car in next year. But the petrol price is rising and rising. i am afraid I can afford it to use it when I buy it. What is more, petroleum resource is limit. So the price will be up and it is impossible to be down. The demanding is big and resource is limit. Who can afford using a car in the future.? It is a big problem.
Buying a car is not a big problem for everyone in the future,I guess. I think I will take the drive lesson and get the drive lisence first in next year. About buying a car, I have to wait for a period.
