As for range:

I agree with JST that ~200-250 miles is the sweet spot for an EV. Anything above that is potentially wasting weight from extra batteries and not needed >95% of the time (and possibly closer to 99% for most people).

I have the now out-of-production S60 -- that originally had an EPA rating of 208 miles, and now displays 195 rated when I do a 100% charge. The drop is partly due to age (the battery is nearing 3 years old...) and partly due to calibration algorithms that are estimates and not always exact (for example a 100% charge I did last December was 188 miles, while last week was 195 -- but the battery was likely holding nearly exactly the same energy). Based on the ~185 mile drive we did last Friday, which had 11 miles remaining, I think 195-196 is accurate and would mean the battery has degraded by 5-6% since new (not bad in 3 years -- Nissan Leafs are known to degrade ~30%+ in <2 years).

Anyway... Out of the nearly 49k miles on the car, about 7.5k has been on road trips -- so 15%. Most of those road trips have used multiple superchargers (a couple were non-supercharger or only 1...). I've found that the pace of a road trip with a ~45 min stop for charging every 1.5-2 hours is really refreshing. You drive for a bit, pull into a supercharger, plug in and go find a place to grab a drink, hit the restroom and sit down and read or take a short walk.
