Description

Calculate the total transit time with a better path, taking into account the path of the trip.
Also, we should send a message to the user if no routing results are found for any destination.

What do you mean by "with a better path"?

[samuel-duhaime]

@tahini I mean, right now the route is calculated from home to the most frequently visited location, but sometimes the second most frequently visited location is right next door, so it's a lot of unnecessary distance (which doesn't represent the actual distance traveled).

The logic should be something like this image instead.

Ce sera compliqué d'inférer des chaînes de déplacement à partir des lieux... on ne sait ni quand ni pourquoi exactement les gens vont en qq part. Même si les lieux sont à côté, ils ne sont pas nécessairement visités en même temps.
