What other charging options are available? This would be the first I've heard of the Tesla network being inferior to the competition.
For some, its not necessarily that the charging network is inferior, but that a supercharger is more out of the way on where they want to go than some other charger. Im in CA so that really doesnt happen (much) here, but even here, there are reasons someone might want to charge at another network for convenience, free charging, its at the restaurant / grocery store Im at, etc.
In this OPs case however, we definitely do not have enough information to see that charging at something other than superchargers is required to complete the trip, and in fact some have posted information showing that there are superchargers around the area they are saying they want to go.
Without the OP at least providing starting and finishing cities or something, there isnt much else we can do to help that we havent already done in this thread.
