For me in addition to inadequate charger and Supercharger coverage, the biggest issue with BEV long-distance driving is indeed the schedule, when there is a schedule. The leisurely roadtrip is one thing, but when one travels for work, it is very hard to suddenly plan around very long charging delays - even optimal ones, let alone delayed ones.
I do it on occasion when there is clearly an A to B meeting, with a Supercharger halfway between A and B, and only one meeting that day, preferably so that I can get from A to B to meeting and back to Supercharger with my home charge so I don't risk a full charger on the way there and risk missing the meeting (I can risk missing dinner in the evening)...
But even then it ends up being a whole day commitment usually, because the charge has to be factored in and I can't usually just combine multiple business hours movements intra day, if they require charging in the middle... When things become any more complicated than that, it has been ICE time for me and still is.
