Actually a few guys took it from Melbourne to Sydney to see how much time the charging take them, it was 4 stops on the way, which is almost 1000km 2 stops of 10 minutes, I stop of 20 min and 1 stop of 30 min that's 70 min in total. I think if someone goes on a 9 to 10 hours road trip, they need ro have thoes breaks anyway. Tesla's super fast charhers are places where people will usually stop for lunch, coffee and toilet breaks. When I travelled with family by road in my accord I almost took the same breaks, so I think it doesn't make a huge difference
