[citation needed] City-owned BKV runs most of the vehicles of the extensive network of surface mass transportation in Budapest, with the emphasis on buses.

The articulated bus is a hallmark of Budapest; both diesel and ETB bendy vehicles have been running since the late 1950s and still form the majority of BKV's fleet.

Completing the eastern sector of M0 beltway around the city in 2008 significantly reduced traffic congestion, the inauguration of metro line M4 in 2014 further helped the situation.

There is a plan for a high-speed rail link to Ferihegy BUD international airport, which is currently served by bus from the end of the metro line M3.

In 2005 a "BEB" monthly pass was introduced for a 10% extra cost over the regular price, which permitted the use of the MÁV national railway lines within the city area, effectively increasing the tracked service for BKV's passengers.

During the Socialist era, Budapest had 2 million residents and its public vs. private transport ratio (the so-called modal split) was 80% : 20% in favor of mass transit.

(After the Iron Curtain fell, a large number of second hand cars were imported from Austria and Western Europe, leading to rapid private motorisation of Budapest's streets.)

In 2016, the more than 30 years old Russian trains running on metro line M3, produced by Mytishchi Machine-building Factory, started to be refurbished by the legal successor Metrowagonmash.

BKV operates on a net-loss basis; state-mandated ticket prices cover less than 50% of running costs.

The state circumvents EU regulations by failing to fully compensate the BKV company for operating costs and amortization.

[4] This method of ticket management had been planned for the entire transit system of Budapest for years, but only now is it materialized.

Most of line M2's stations only have escalators, excluding Puskás Ferenc Stadion, Pillangó utca and Örs vezér tere.

In 2009-2010 investigations[15][16] into corruption led the police examine all money logs and contracts of the 20-year period individually, to find issues unrelated to the already detected ones.

This issue led the owner, the Local Government of the Capital City making BKV accept a new Company Inner Regulation System and its assembly enacting local government degrees guaranteeing complete transparency in the contracts, billings, and job descriptions for the owner, and for all representatives of its assembly even individually.

The ironic beginning of the movie features Botond Aba, former CEO of BKV, who declares that all events and locations shown in the film are purely fictional.
