Why do you say that cabs bring down the quality of drivers in the whole city? That's just an individual, it has nothing to do with whether it's a cab or not, some drivers of private cars drive on the road with the same feeling that the road is my home to drive on. Also, I'm not particularly sure which aspect of driver quality you're asking about, if it's driving erratically, then a lot of people drive erratically, and if it's mannerisms, maybe some drivers talk vulgarly, but that doesn't represent an entire industry, or even an entire group of people.
Sometimes when you take a cab, you do encounter that kind of bad thing, for example, once I went out with my friends to a tourist city to play, the city is not particularly familiar with, want to find a more authentic local restaurants to eat some of the characteristics of the food. It's a good idea to take a cab, this master heard, on the eloquent, said they are local to go to which where to eat , but also blame us simple, but also really believe that he said, and then to the place, only to find that the master is a TO . Although it did not do anything bad, but the feeling is still quite disappointed.
But there are good cab drivers, I remember seeing a video of a taxi driver, pulling a job on the road, meeting a middle-aged man, walking along the road with a bag for a long time. He went to accost, it turned out that the middle-aged man working outside, not a penny, intend to walk a long way home, the master let him get on the car, free to send him home, can we say that the master of the quality is low?
Looking at people don't just look at them doing something you're not happy with, and say that they're pulling down the quality of the whole group, the quality of which is not unique to a particular industry, but to the individual.
