The iconic London black cab has been voted the world’s favorite taxi for the sixth year in a row, for everything from cleanliness, knowledge of the city and quality of driving.

London taxis beat out the equally iconic yellow cabs in New York in Hotels.com’s global taxi survey, taking 22 percent of the vote.

British taxi drivers swept five of the seven categories, taking the top spot for cleanliness, quality of driving, friendliness, safety and knowledge of the city.

In order to become licensed as a cab driver in London, drivers must pass a training course that’s been described as the most demanding in the world, as they must know 320 routes within a six-mile (10 km) radius of Charing Cross.

For the more than 2,680 respondents across 30 countries, safety is the most important element when climbing into a cab, followed by value, knowledge of the area, availability and quality of driving.

While the most common activity performed in a cab is to send texts or emails, the survey also managed to find that Brits are the most likely to cop a feel and a snog during the drive, with 14 percent admitting to randy backseat behavior — 10 percent above the global average.

And like with hotels, the most important feature for taxi riders is wifi access, which beat out the radio and music.

Meanwhile, cities around the world are increasingly tapping into the vast street knowledge of their cabbies, training drivers to pull double duty and play tour guide.

Dubai is the latest city to train its fleet of drivers, teaching them about key landmarks, hotels, events and attractions in the city. Tokyo, London and Edinburgh also have put similar programs in place.

Here’s the ranking for the world’s best taxis:

1. London, 22 percent of votes
2. New York, 10 percent
3. Tokyo, 9 percent
4. Berlin, 5 percent
5. Amsterdam, Madrid and Mexico City, 4 percent
