left and right根据定位句可知，有研究表明女性司机很难辨别左右的时候。故填入left and right。

Some people believe that women are better drivers than men.
    However, others think that women make worse drivers. In one survey of 3,000 male drivers in the UK, most felt they were better drivers than women in their lives. The idea that women make worse drivers is a stereotype. It comes from a time when women drove less than men. And driving was seen as a man* s responsibility. There are certainly different views on this controversial question although there are a number of reasons why a woman’ s personality makes her a more competent driver. Firstly, women are more patient and polite towards other road users, such as pedestrians and cyclists. In stressful situations, they are more likely to stay calm and less likely to be involved in road rape incidents. Secondly, female drivers are more cautious and therefore take fewer risks, for instance, when overtaking. Thirdly, they are more responsible so they tend not to drive when tired or after drinking alcohol.
    On the other hand, many people argue that women cause accidents, because they can be indecisive or react slowly, because they lack confidence. ln addition, they are easily distracted. For example, by children in the car, scenery or other drivers, research also shows that women find map reading more difficult than men and can have problems with the difference between left and right. Despite the fact that women have more accidents, insurance is often cheaper for them, because the accidents tend to be minor. In particular, women have more accidents when parking. This is because women often have poor spatial awareness. In contrast, men tend to have more serious accidents.
    To sum up women, make safer drivers than men because of their personality. This is supported by the fact that women have fewer, serious accidents and pay lower insurance premiums than men.
    Overall, it is clear that women are less competitive and aggressive than men behind the wheel. And therefore, better drivers.
