Speed Limit Alert.
Google regularly updates its Android Auto car platform, but does not always make announcements about it. And now, Android Auto users have noticed the emergence of a new convenient feature.
Speed limit alerts have been available on the Google Maps mobile app for a long time, but they haven’t been displayed on Android Auto systems before. Now Android Auto has started displaying speed limits when using Google Maps navigation. The feature is already available for most users.

The first to notice the innovation were users of the social news resource Reddit. It is interesting that the very first lucky ones got it a few ago, but the bulk is only now.
