When Danny is captive in the Taxi, they stop at a zebra crossing on Circus Road at the junction with St Anne's Terrace. They then go straight on down St John's Wood Terrace. After a quick cut shot to Danny, the Taxi is next shown at another zebra crossing at the same junction, only this time they are on St John's Wood High Steet. They then turn left back on to Circus Road and go back the way they had come from. It's not physically possible to get from one of these locations to the other without travelling at least half a mile down St John's Wood Terrace before even attempting to get back to that junction, but especially impossible to do it in the short duration of the cut shot.
