Which street in the UK is the only place where vehicles are required to drive on the right?

The Savoy is a luxury hotel located in the Strand in the City of Westminster in central London, England. It was the first luxury hotel in Britain, introducing electric lights throughout the building, electric lifts, bathrooms in most of the lavishly furnished rooms, constant hot and cold running water and many other innovations.

Savoy Court is the only named street in the United Kingdom where vehicles are required to drive on the right. This is said to date from the days of the hackney carriage when a cab driver would reach his arm out of the driver's door window to open the passenger's door (which opened backwards and had the handle at the front), without having to get out of the cab himself. Additionally, the hotel entrance's small roundabout meant that vehicles needed a turning circle of 25 feet (7.6 m) to navigate it. This is still the legally required turning circle for all London cabs.
