Emergency services do not (typically) use Google Maps. They use special navigation services that can plot optimal routes while ignoring certain traffic rules. For example, fire trucks can and will go the wrong way down a one-way street; something Google Maps will not account for.

Exactly, what I tried to say is that emergency services (particularly search and rescue on sea) have to go out and save people who were in a boat and relying on Google Maps or Apple services (in the old times, the same people would navigate coastal waters with a map torn out of a phone book).

The SAR teams themselves of course have dedicated equipment and the staff are required to master traditional navigation skills so they can find their way around even without that equipment.
