Cars and bicycles are similar in that they are both privately owned means of transport.
However,there are a lot of differences between them.A car costs a lot more to buy than a bicycle.In addition,it is far more expensive to run.For example,a car has to be insured,and must be served regularly~further more,spare parts for a car cost a lot of money.A car uses petrol,which is expensive,where as a bicycle uses only human energy.
On the other hand,as far as comfort is concerned,a car is better than a bicycle.In a car you are protected from the weather,and have comfortable seats and plenty of room to carry people and luggage.
A car is not only more comfortable than a bicycle,it is faster as well.
With respect to convenience,it is difficult to say which one is better.A bicycle is certainly easier to park!
So it is difficult to make a choice.In my opinion,if you can afford it,you'd better buy both a car and a bicycle.It will be very convenient.
