London has two kinds of taxi:
The Black cabs, famous black cabs in London, can be taken anywhere, with total security, provided they have their luminous sign on. Although not all are black. They charge a 10% supplement for carrying luggage and at night and on weekends they raise their rates. You can even trust them to deliver packages without any risk.
To the Mini cabs It is better to hire them in the offices or by phone as their drivers may lack insurance or not know the city correctly. An exception are the Lady cabs, which provide a careful and close service. With male or female drivers, at the passenger’s request. They deal with trips for children without company or for people who require special care.
