Starting with a conclusion and working backwards is often a good way to plan a composition.

Introduction

My experience certainly reflects the statement above. When I was a child, the centre of my city was quite a pleasant place to visit. There was quite a lot of traffic, but it was possible to move around the city reasonably freely. Now, just a decade or so later, the situation has changed dramatically. Much of the centre is continuously choked with traffic, and it can be very time-consuming to travel even short distances.

Body paragraph 1

Clearly something has to be done to solve this kind of problem. In my city the authorities tried limiting city centre traffic to cars belonging to local residents, but the scheme has not been a big success. Many other people just drive into the city anyway, and cheerfully pay the small fine on the rare occasions when they are caught.

Body paragraph 2

Another possibility is charging drivers to use particular roads. However, this can create logistical problems. Collecting the payments requires a complicated technological system of some kind, and drivers are likely to switch to free routes instead, merely relocating the congestion..

Body paragraph 3

It seems to me that it is human nature to try and find ways around rules and regulations. If, for example, the government made petrol a lot more expensive, it would probably create a black market in tax-free petrol. If the government limited new car registrations to, say, half-a-million new vehicles a year, people would simply keep their old cars running for longer.

Conclusion

The solution to this problem is not government action alone, although that can help, but self-government. We should all consider whether each car journey is really necessary. When a journey is genuinely necessary, we should then ask ourselves whether it would it be just as quick and easy to use public transport instead, or even walk. Human beings do have legs, although many people I know seem to have forgotten this fact.
