Today’s navigation solutions- even though they give you turn by turn audio instructions – still require that you take a look at the map because the instructions are too general and many time can be understood in more than one way.
Use user generated audio instructions as an additional aid to the standard ones. These will be very specific to the particular place (for instance: “take the later right turn from the two you’ll see”) as opposed to the standard one (like “turn right.”)
Save you the trouble of going there and waiting.
Add live information to navigation software that includes the estimated waiting time at gas stations on your way.
You are about to fly for a vacation and realized you don’t know enough about your destination.
Sell small cheap tablets at airports that have comprehensive written and video information about destinations, plus a GPS navigation software. You pick up the tablet with your destination or have multiple destinations uploaded to the tablet on the spot in minutes, and when you finish your vacation, you still have a tablet you can use for other things. You can also sell internet access packages to include with the tablet for the destination mobile system.
It’s irritating, especially when you are in a hurry (always.)
Have people signal they are driving a vehicle in a “learning mode,” and let navigation systems like Waze help you plot a route avoiding them.
