When doing any long distance driving, you better have a backup charging station to your backup charging station.
We always do. If not, we take the gas pickup. To your point, I'd add to that and say before buying an EV one should look at most of the long trips you take and research if they have good charging options. If not, don't buy an EV. In our case, virtually all of our long trips have plenty of fast charging options. Thus 2 years ago when it was time to replace my wife's car anyway, we got an EV. If most of our trips were through sparsely populated areas it would have been unwise to get an EV.
Even with that, I still wouldn't advise an EV unless you do lots of local driving that you can charge from home. The gas savings and oil change savings of an EV are real --- as long as you regularly drive plenty of miles for the gas savings to be worth the costs of an EV. IMHO, based on the past year's worth of gas and power costs in Alabama, I'd say that's about 12K miles or more per year. In the 2 years we've had our EV we've put 49K miles on it -- over 24K miles per year.
