If you use Google Maps only when driving, keep in mind that it can help you find the quickest walking or biking routes in a city. Not to forget that you can access the public transport schedule straight from the app. All you need to do is to find the nearest bus or train station, click on it, and you will get the timetable. This option might not be available in some smaller towns but you can be certain that you can access it in every large city.
