Technology has become an important and helpful thing in our society, and cars are the most famous technology nowadays. So, I will talk about the benefits of cars. First, if you have a car, your transportation will be easy and fast. So you will save your time. second, cars can pick up you from city to another, but you should watch up the street while you are driving at night. I think that cars are very helpful but also the are some disadvantages. In my opinion the traffic is a big problem , and sometimes it makes you be late. Also cars make our society pollute, but we can’t live without cars, so we should try to turn out new cars that be eco-friend.
