A spokesperson for StressFreeCarRental.com said: “It’s unsurprising to see the most densely populated city at the top of the league table – with New Yorkers travelling at an average of 12 miles an hour at rush hour.

“Of the top 10, it’s only drivers in Pittsburgh and Miami who can make a six mile journey in less than 15 minutes.

“For motorists in the most congested cities of San Francisco, Washington DC, and New York, the journey will take 20 minutes or more.

“Drivers are experiencing slow moving traffic every day – with an average speed of only 17.5 mph during rush hour across the US as a whole.

“And many motorists are spending over 40 minutes doing their daily commute because of how congested the city roads have become.

“This is frustratingly slow and none of us particularly enjoy spending longer than we already do sitting in our cars while we miss out on things we would rather be doing instead.

“But it is surprising not to see some of America’s busiest cities on the list – Pittsburgh ranking above Los Angeles is surprising when you consider the reputation LA has for congestion.

“What we might be seeing is the result of differing levels of investment into improving roads and public transport city to city.

“As the US tries to improve its air quality, pollution, and reduction of emissions, we need more investment to help traffic flow more freely.

“This might involve introducing more congestion charges for motorists in these cities and pumping more funding into improving roads and public transport systems to tackle the issue.”
