You are actually talking about a different althought related problem. First of all, the government authorized taxis are far less in number than needed to fulfill the needs. That is a key problem. We need to resolve that one first. Yes, then we have to think about the quality of service that these cars and their drivers deliver. Of course, that is equally important. However, the private, illegal taxi drivers are in business not because the legal ones are rude, or improperly trained. It mainly because the legal cabs are too less in number.
