Even relying too much on any navigational aid can be harmful. I've been in foreign cities using Google Maps or Waze and they've had streets marked as one-way but the wrong way, so I almost went on that street if I hadn't spotted the signs. Even when using the correct mode, or whatever, you should always look at the available signage, and you should be in the clear.
