Citation about taximeters in Wikipedia
Taximeters can include several accessories, or act as components in larger dispatching/control systems. Features include:
Fraud control and prevention (on the part of the owner or operator), through the impression of control tickets or computer monitoring. Additionally, taximeters are often visually sealed by a municipal weights and scales authority after initial calibration.
Radio communication, allowing trip status to be monitored by a dispatcher or supervisor.
Dispatching of trip assignments through radio or data systems.
Interaction with GPS systems to assist with dispatching and to provide security.
Seat sensors that detect the presence of a passenger (to prevent a cab from carrying fares without activating the taximeter).
Credit or prepaid card support.
Wikipedia and taxicab
A taxicab, also known as a taxi or a cab, is a type of vehicle for hire with a driver, used by a single passenger or small group of passengers, often for a non-shared ride. A taxicab conveys passengers between locations of their choice.
This differs from other modes of public transport where the pick-up and drop-off locations are determined by the service provider, not by the passenger, although demand responsive transport and share taxis provide a hybrid bus/taxi mode.
Wikipedia about pet taxi
A pet taxi is a type of transportation taxi service that transports various pets. Some pet taxi services also provide pet ambulance, animal boarding and grooming services. Some pet sitting companies may also offer pet taxi services. Some pet taxis charge by the mile, while others may offer a flat rate for various trips. Less commonly, some pet taxi services may offer long-distance pet transportation, such as a trip from New York City to Florida.
Trip itineraries may include trips to veterinarians, pet sitting services, kennels and pet spas. Transportation to and from airports may occur because standard taxicabs may not allow pets. Clientele may include people who don't have time or a means to transport their pets.
