If you’ve spent any time driving in London – and yes, I do mean even as little as a few minutes – you’ll be familiar with our city’s infamous traffic. From streets backed up with bumper-to-bumper traffic to seemingly never-ending road closures and diversions, the traffic never seems to end. And now recent research has confirmed our congestion-based fears, with London officially home to the most congested roads in Europe.
Inrix, which analyzes traffic and mobility data around the world, recently released its 2023 Global Traffic Scorecard, which contained the damning information. The report looks at “three years of mobility data” across over 900 cities in 37 countries to determine which city has the worst traffic and congestion. And London didn’t do too well…

According to the report, Londoners who travel by car lose an average of 99 hours to traffic and congestion. In the middle of the city, average speeds are just 10 miles per hour, and it’s estimated that traffic costs drivers a whopping £902!
