Tokyo has begun quietly testing out USB ports on a single bus in its metro area, according to the Japanese publication IT Media. There’s been no official word from Tokyo transportation authorities, and given that the test includes only one bus, that isn’t too surprising. But what is shocking is that USB ports on public transportation aren’t commonplace in 2017.

There have been a few cities, such as Singapore and London, that have run small trials with USB ports on city buses over the past few years, according to The Next Web. But somehow, despite there being billions of smartphones in the world, USB ports aren’t a standard part of any bus fleet — except for New York City, which is currently rolling out a fleet of new tech-friendly buses that should make commuting a bit less stressful for passengers.

Hopefully New York City won’t be the only city for long. Smartphones have been commonplace since 2009; airplanes, cars, and even taxis have jumped on the USB port wave. It’s time that public transportation like buses and subways did the same thing on a large scale.
