Yes, London black cab drivers are still required to pass "The Knowledge" as of 2026. This legendary test, which requires memorizing 25,000 streets and 100,000 landmarks within a six-mile radius of Charing Cross, remains the gold standard for taxi licensing. While Transport for London (TfL) has introduced digital modules and virtual mapping tools to modernize the learning process, the core requirement for "geographic recall without aid" remains unchanged. Drivers spend an average of three to four years on scooters traversing the city to master these routes. This rigorous training is why black cabs are legally allowed to be hailed on the street, unlike private hire vehicles like Uber, which rely solely on GPS. The depth of this mental mapping even causes physical changes in the drivers' brains—specifically an enlarged hippocampus—proving that even in the age of AI, the human expert still holds a vital place in London's transport infrastructure.
