For the second year in a row, London was the slowest city to drive in 2023. The capital of England has the lowest base speed due to the static factors, such as the absence of any fast road, and speed limits changed to 20mph on most roads over the past years - so, even in optimal traffic conditions, the average speed in London is slower than any other city in the world.

London's road infrastructure is not the only reason why travel times are slower than in any other city in the world: London is also the city in which motorists have lost the most time due to traffic congestion. A 6-mile journey in 2023 is 12 minutes and 5 seconds longer on average than the optimum journey time (i.e. with no traffic at all).
