A possible version:

These days many high school graduates are learning driving during their summer vacation. In my opinion , learning to drive a car is a very positive experience for an individual. Knowing that you are able to drive makes you more confident. Also, ability to drive gives you independence, which means you can go wherever and whenever you want. It is much more convenient and quicker to get around in a car than to wait for a bus.

On the other hand, it is sometimes difficult to find a parking place in the city with the number of cars increasing so fast. Besides, it can be expense—not just to buy a car, but also to pay for petrol and all the repairs your car will need. Apart from that, lack of experience may get you into a car accident. If so, it will be wiser to take a bus.
