Split distance and speed units
Give the capacity to a user to select the units (miles or Km) separately for distances and speed. As an example, some European users in the UK are used to navigate in Km but the speeds limits are set in miles. The actual settings will not let you have different units set for speed and distance. I believe this easy feature will be very welcomed by many users.

As an International traveller who uses hire cars and Waze, I would like to be able to set Waze up to tell me distances in METRIC and set my speed to be reported in MILES.
This way, I can relate to the dashboard (which is always in MPH or KPH) AND I can confidently judge how far the next turn is...(personally I have no sense of a 1/4 of a mile but I instinctively know how far 400 metres is).
At the moment, I believe can only have either METRIC or IMPERIAL and it is set for both SPEE AND DISTANCE.
