Even when looking at non-exotica every-day vehicles like current-gen nissan leaf you get ~200 miles of range, and can recharge 240mph (more than 4 miles per minute) [1] More recent cars getting launched now (and again, not necessarily exotic brands, but even Hyundai and VW) have even faster charging rates.
So even a 15 minute break for the toilet and getting a takeout coffee will give you 60 miles of range. Stop for 45mins for lunch? Add 180 miles of charge, or 3 more hours of driving at 60 when you might want to stop again for a toilet break or to stretch your legs.
If you truly need to drive for 7 or 8 hours (400-500 miles at 60) without any kind of significant breaks on a regular basis, then I'd argue that you are probably taking quite a risk to your safety (and those around you - both inside and outside your car) due to tiredness.
