This information is from Wikipedia, Its only about the evaluation of Taxies/Hackney carriages. Am srry if this story gets a little long, I like to include as much information as possible. Just so it doesn't look like i stopped the post mid paragraph.

Hackney carriages!

Horse-drawn for-hire hackney carriage services began operating in both Paris and London in the early 17th century. The first documented public hackney coach service for hire was in London in 1605. In 1625 carriages were made available for hire from innkeepers in London and the first taxi rank appeared on the Strand outside the Maypole Inn in 1636. In 1635 the Hackney Carriage Act was passed by Parliament to legalise horse-drawn carriages for hire. Coaches were hired out by innkeepers to merchants and visitors. A further "Ordinance for the Regulation of Hackney-Coachmen in London and the places adjacent" was approved by Parliament in 1654 and the first hackney-carriage licences were issued in 1662.

A similar service was started by Nicolas Sauvage in Paris in 1637. His vehicles were known as fiacres, as the main vehicle depot apparently was opposite a shrine to Saint Fiacre. (The term fiacre is still used in French to describe a horse-drawn vehicle for hire, while the German term Fiaker is used, especially in Austria, to refer to the same thing.

Hansoms!

The hansom cab was designed and patented in 1834 by Joseph Hansom, an architect from York as a substantial improvement on the old hackney carriages. These two-wheel vehicles were fast, light enough to be pulled by a single horse (making the journey cheaper than travelling in a larger four-wheel coach) were agile enough to steer around horse-drawn vehicles in the notorious traffic jams of nineteenth-century London and had a low centre of gravity for safe cornering. Hansom's original design was modified by John Chapman and several others to improve its practicability, but retained Hansom's name.

These soon replaced the hackney carriage as a vehicle for hire. They quickly spread to other cities in the United Kingdom, as well as continental European cities, particularly Paris, Berlin, and St Petersburg. The cab was introduced to other British Empire cities and to the United States during the late 19th century, being most commonly used in New York City.

The first cab service in Toronto, "The City", was established in 1837 by Thornton Blackburn, an ex-slave whose escape when captured in Detroit was the impetus for the Blackburn Riots.

Modern taxicabs!

The modern taximeter was invented and perfected by a trio of German inventors; Wilhelm Friedrich Nedler, Ferdinand Dencker and Friedrich Wilhelm Gustav Bruhn. The Daimler Victoria—the world's first motorized-powered taximeter-cab—was built by Gottlieb Daimler in 1897 and began operating in Stuttgart in June 1897. Gasoline-powered taxicabs began operating in Paris in 1899, in London in 1903, and in New York in 1907. The New York taxicabs were initially imported from France by Harry N. Allen, owner of the Allen-Kingston Motor Car Company. Their manufacturing took place at Bristol Engineering in Bristol, Connecticut where the first domestically produced Taxicabs were built in 1908, designed by Fred E. Moskovics who had worked at Daimler in the late 1890s. Albert F. Rockwell was the owner of Bristol and his wife suggested he paint his taxicabs yellow to maximise his vehicles' visibility. Moskovics was one of the organizers of the first Yellow Taxicab Company in New York.

Electric battery-powered taxis became available at the end of the 19th century. In London, Walter Bersey designed a fleet of such cabs and introduced them to the streets of London on 19 August 1897. They were soon nicknamed 'Hummingbirds' due to the idiosyncratic humming noise they made. In the same year in New York City, the Samuel's Electric Carriage and Wagon Company began running 12 electric hansom cabs. The company ran until 1898 with up to 62 cabs operating until it was reformed by its financiers to form the Electric Vehicle Company.

Taxicabs proliferated around the world in the early 20th century. The first major innovation after the invention of the taximeter occurred in the late 1940s, when two-way radios first appeared in taxicabs. Radios enabled taxicabs and dispatch offices to communicate and serve customers more efficiently than previous methods, such as using callboxes. The next major innovation occurred in the 1980s when computer assisted dispatching was first introduced.

As military and emergency transpor!

Paris taxis played a memorable part in the French victory at First Battle of the Marne in the First World War. On 7 September 1914, the Military Governor of Paris, Joseph Gallieni, gathered about six hundred taxicabs at Les Invalides in central Paris to carry soldiers to the front at Nanteuil-le Haudouin, fifty kilometers away. Within twenty-four hours about six thousand soldiers and officers were moved to the front. Each taxi carried five soldiers, four in the back and one next to the driver. Only the back lights of the taxis were lit; the drivers were instructed to follow the lights of the taxi ahead. The Germans were surprised and were pushed back by the French and British armies. Most of the taxis were demobilized on 8 September but some remained longer to carry the wounded and refugees. The taxis, following city regulations, dutifully ran their meters. The French treasury reimbursed the total fare of 70,012 francs. The military impact of the soldiers moved by taxi was small in the huge scale of the Battle of the Marne, but the effect on French morale was enormous; it became the symbol of the solidarity between the French army and citizens. It was also the first recorded large-scale use of motorized infantry in battle.

The Birmingham pub bombings on 21 November 1974, which killed 21 people and injured 182, presented emergency services with unprecedented peacetime demands. According to eyewitness accounts, the fire officer in charge, knowing the 40 ambulances he requested were unlikely to be available, requested the Taxi Owners Association to transport the injured to the nearby Birmingham Accident Hospital and Birmingham General Hospital.

Vehicles!

Taxi services are typically provided by automobiles, but in some countries various human-powered vehicles, (such as the rickshaw or pedicab) and animal-powered vehicles (such as the Hansom cab) or even boats (such as water taxies or gondolas) are also used or have been used historically. In Western Europe, Bissau, and to an extent, Australia, it is not uncommon for expensive cars such as Mercedes-Benz to be the taxicab of choice. Often this decision is based upon the perceived reliability of, and warranty offered with these vehicles. These taxi-service vehicles are almost always equipped with four-cylinder turbodiesel engines and relatively low levels of equipment, and are not considered luxury cars. This has changed though in countries such as Denmark, where tax regulation makes it profitable to sell the vehicles after a few years of service, which requires the cars to be well equipped and kept in good condition.

Cities like London and Tokyo have implemented specific regulations like London's Conditions of Fitness that dictate size, fuel efficiency, emissions, and accessibility standards far stricter than that for private vehicles. Much like the NY Checker cabs of the 60s–80s, the unique attributes of the city often make the vehicles built to fit those requirements ubiquitous to its livery fleets, and often becomes an iconic image of the city itself.

Although New York City's efforts to implement new regulations has stumbled in its efforts to mandate both a hybrid and wheelchair-accessible vehicle,[30] London and Tokyo's efforts have yielded unique vehicles such the LEVC TX and Toyota JPN Taxi that meet and exceed modern emissions and accessibility requirements for the future, and will hopefully soon extend to other cities as older models get rotated out of the bigger cities and into smaller markets. Modifications of existing minivans such as the Mercedes Vito London Taxi and the Nissan NV200 have been introduced as a stopgap measures to fill the need for alternative products, however their acceptance by drivers is yet to be seen.

Wheelchair-accessible taxicabs!

In recent years, some companies have been adding specially modified vehicles capable of transporting wheelchair-using passengers to their fleets. Such taxicabs are variously called accessible taxis, wheelchair- or wheelchair-accessible taxicabs, modified taxicabs, or "maxicabs".

Wheelchair taxicabs are most often specially modified vans or minivans. Wheelchair-using passengers are loaded, with the help of the driver, via a lift or, more commonly, a ramp, at the rear of the vehicle. This feature is however a subject for concern amongst Licensing Authorities who feel that the wheelchair passenger could not easily exit the vehicle in the event of accident damage to the rear door. The latest generation of accessible taxis features side loading with emergency egress possible from either of the 2 side doors as well as the rear. The wheelchair is secured using various systems, commonly including some type of belt and clip combination, or wheel locks. Some wheelchair taxicabs are capable of transporting only one wheelchair-using passenger at a time, and can usually accommodate 4 to 6 additional non-disabled passengers.

Wheelchair taxicabs are part of the regular fleet in most cases, and so are not reserved exclusively for the use of wheelchair users. They are often used by non-disabled people who need to transport luggage, small items of furniture, animals, and other items. Because of this, and since only a small percentage of the average fleet is modified, wheelchair users must often wait for significantly longer periods when calling for a cab, and flagging a modified taxicab on the street is much more difficult. London's taxis have been fully accessible since January 2000, with all taxis fitted with a pull-out or portable ramp.

Other!

Taxicabs in less developed places can be a completely different experience, such as the antique French cars typically found in Cairo. However, starting in March 2006, newer modern taxicabs entered the service operated by various private companies. Taxicabs differ in other ways as well: London's black cabs have a large compartment beside the driver for storing bags, while many fleets of regular taxis also include wheelchair accessible taxicabs among their numbers (see above). Although taxicabs have traditionally been sedans, minivans, hatchbacks and even SUV taxicabs are becoming increasingly common. In many cities, limousines operate as well, usually in competition with taxicabs and at higher fares.

Recently, with growing concern for the environment, there have been solar powered taxicabs. On 20 April 2008, a "solar taxi tour" was launched that aimed to tour 15 countries in 18 months in a solar taxi that can reach speeds of 90 km/h with zero emission. The aim of the tour was to spread knowledge about environmental protection.
