Google Now might not be as well known as Apple’s Siri, but the intelligent personal assistant app has a few cool features up its sleeve. One of those is a new update that, according to an article published by PC Magazine, will alert sleepy public transportation travelers know when their transit stop is coming up.

PC Magazine outlined a scenario likely a familiar to people who often go out drinking with friends and night and then head back home on subway trains or buses. Sleep strikes all too easily at the end of these late night, intoxicated adventures, and many people have nodded off, eventually riding public transportation miles and miles past their destination. Mistakes like these result in the loss of money, time, and irritation; and they are not limited to nights of drinking either. On the contrary, in big cities where public transportation is the norm, long rides easily beget sleep, potentially leading passengers that very dilemma.

A new update to Google Now, though,  seeks to prevent mistakes like these from ever recurring. It is not yet clear precisely how the feature works, but ostensibly, Google Now will be able to sense when you are using public transportation. In other words, shortly after you start riding the bus or subway, Google Now will jump to life, asking if you want to set an alarm to alert you when your stop is near. When the public transit route winds near to your jump-off point, whether for work, school, or home, the alarm will go off, jerking you out of your slumber and telling you the time has come to disembark.

The new update will soon be available to Google Now users on Android. It remains to be seen whether the feature will be able accessible everywhere, or only in select major cities.
