Using an app while driving is dangerious. Most places illegal as well. The charger will be within 50 miles but you won't find it without the app which means annoying. And if you forgot your phone you are in trouble.
replyyou're making silly arguments. it's not anymore dangerious/illegal than using the gps for google/apple maps.
replyIf the gps is settup before you start and not touch until you are there it is safe.
replyif you are facing a strong headwind you will not make it to your preplanned charger.
