Taxis may vary in their quality and cleanliness, depending on the driver and the company. Some taxis may be old, dirty, or poorly maintained. Some taxi drivers may be rude, dishonest, or unprofessional. Taxis may not be easily available in some areas, such as rural or suburban locations, or during bad weather or special events. Taxis may also be scarce during high demand periods, such as rush hours or holidays.
