Not often, but we're not going to buy 2 separate cars, 1 for regular trips and one for road trips.
Range anxiety is a thing, especially since the "failure mode" is really bad. Super chargers are really rare compared to gas stations and if you run out of battery, with regular charging it takes 10 hours to charge.
Maybe 880km is too much, but for sure I'd want 60% (so 660km) + something extra, maybe 50-80km, to not feel anxious when driving long distance.
Plus overnight charging is unfortunately still a problem.
I personally think that for me (and I guess many others), the next generation of EVs or maybe the facelift for the current generation should be really close to what I want. By next generation I mean that many EVs are/will be launched soon (so 2020/2021/2022), in the car world a generation is usually around 7-9 years (so 2027-2031), and a facelift is done usually mid-cycle (so probably 2025-2026).
I've found re-charging on long journeys to be ok although it helps to have a plan A and a plan B and for best results you combine charging with lunch or something. But I do live in Europe where distances are shorter and chargers are more plentiful
You've got to remember that with an EV, you start every day with a full 'tank'*
(* as long as you've got somewhere to plug it in overnight, which is a problem in some places, granted)
