Google is updating Google Maps on Android to introduce another useful feature. After the company introduced the ability to see speed cameras, it’s now adding an actual speedometer to the Maps app.
That means when you are driving, you will be able to keep an eye on your own speed, along with the local speed limit. Android Police reports that the feature isn’t enabled by default, and it’s only available in some regions, including Argentina, Australia, Belgium, Brazil, Canada, Czech Republic, Finland, Germany, India, the Netherlands, Poland, Portugal, Sweden, Taiwan, UK, and the US.
The feature can be enabled through the Navigation settings under Maps’ preferences and doesn’t work with Android Auto just yet. But here’s the thing: Google is using GPS to calculate your speed, so I wouldn’t fully rely on the speedometer while driving. GPS isn’t fully reliable when it comes to calculating a car’s speed, so you are probably better off looking at your car’s actual speed from the dashboard.
