The police car that chases the conductor's stolen car through Cardiff carries UK national police high visibility livery (aka 'battenburg'). The film is set in 1997, and though one or two UK police forces had began rolling it in by then, South Wales Police (who police Cardiff) did not introduce it until about 1999/2000, so would still have been using their regional livery at the time (a band consisting of a two-tier red and white check).
