  Although the majority of journeys in central London are made by public transport, car travel is common in the suburbs. The inner ring road (around the city centre), the North and South Circular roads (just within the suburbs), and the outer orbital motorway (the M25, just outside the built-up area in most places) encircle the city and are intersected by a number of busy radial routes—but very few motorways penetrate into inner London. The M25 is the second-longest ring-road motorway in Europe at 117 miles (188 km) long. The A1 and M1 connect London to Leeds, and Newcastle and Edinburgh.
  
  The Austin Motor Company began making hackney carriages (London taxis) in 1929, and models include Austin FX3 from 1948, Austin FX4 from 1958, with more recent models TXII and TX4 manufactured by London Taxis International. The BBC states, "ubiquitous black cabs and red double-decker buses all have long and tangled stories that are deeply embedded in London's traditions". Although traditionally black, some are painted in other colours or bear advertising.
  
  London is notorious for its traffic congestion; in 2009, the average speed of a car in the rush hour was recorded at 10.6 mph (17.1 km/h). In 2003, a congestion charge was introduced to reduce traffic volumes in the city centre. With a few exceptions, motorists are required to pay to drive within a defined zone encompassing much of central London. Motorists who are residents of the defined zone can buy a greatly reduced season pass. Over the course of several years, the average number of cars entering the centre of London on a weekday was reduced from 195,000 to 125,000.
  
  Low Traffic Neighbourhoods (LTN) were widely introduced in London, but in 2023 the Department for Transport stopped funding them, even though the benefits outweighed the costs by approximately 100 times in the first 20 years and the difference is growing over time.
