It generates a ~10km route in my Canadian city that starts off in meters, and switches to miles. I know we're somewhat used to flipping between metric and imperial, but it's not a common thing to do mid-trip.
Edit: Thanks everyone for the feedback! Just pushed a quick fix:
- USA now defaults to miles & feet
- Canada and Mexico now default to km & metres
- Britain defaults to miles & metres (as before, yes we're weird)
- mainland Europe, Australia and NZ default to km & metres (as before)
The USA should be feet and miles.
Canada should be metres and kilometres.
But you did say North America, it seems these might use miles per hour for road speeds, so they might not want metres and kilometres. I don't know if they want feet, yards or metres though.
