Maybe it's vey niche, but I'd like an "avoid traffic lights" setting. On common routes for me you'd often be a lot faster by going 1 minute out of your way to prevent a potential 5 minute wait at a traffic light during rush hour.
Interesting, I was just going to say how varied and incredibly tasty the local Lao bananas are. I wonder if we have different taste or you've tried different ones than I have.
The ones I like best are the very small "good smelling bananas" (ກ້ວຍຫອມ).
