At least here in Europe there are laws (for commercial drivers) about how long you are allowed to drive for, and when you must take breaks, e.g.:
> "you must not drive more than: 9 hours in a day - this can be extended to 10 hours twice a week"
> "a break or breaks totalling at least 45 minutes after no more than 4 hours 30 minutes driving"
Perhaps the US has zero laws in this regard, but these sort of rules exist due to lots of lessons learned by tired drivers killing people. Sure these are for commercial drivers, but I'd argue that if you are doing this sort of long-distance driving frequently (i.e. not just once or twice a year) then you are no different from a commercial driver and shouldn't assume these common sense laws don't apply.
Driving long distance when there's nothing around (eg the M6 between Preston and Glasgow) is so much simpler. You can definitely drive longer when you're not constantly negotiating city-adjacent traffic.
> Size of the country has no impact on this - people become tired and distracted during long drives.
But size of the country (and more importantly, density) has a massive impact on how far people drive and how frequently.
You can have multiple drivers sharing the same vehicle. This is a common occurrence in both commercial and non-commercial situations (e.g. a family trip with two adults alternating driving and rest periods). With 3-4 drivers on hand, either traveling with the vehicle or trading off along the way, a vehicle can be operated continually without any safety concerns, making the EV with its limited endurance and long recharge times the weakest link.
The Tesla Model 3 can easily add 100 miles in 10-15 mins if its battery is 30% or lower. That isn't theoretical performance, that's actual real-world performance that I've seen. That plus the ~250 miles of range the Model 3 LR has (again real-world range, without making any effort to conserve energy) means you can realistically to your ~350 mile trip with little to no change to total trip duration.
Now the Model 3 may be a premium vehicle, but EV development is only just getting started. Within the next few year we'll be seeing cars with similar performance for half the price. That tied with the rapid expansion of 150kw and 250kw chargers means that in the next 5 years, doing your theoretical road trip, with only one 10-15min break, will be possible in almost any new ~$30k electric car.
An EV charger requires minimal infrastructure compared to a gas pump, and zero attendances. That means that supermarkets etc can just convert normal parking spaces to chargers. Reducing the need for quick charging because people will shop while they charge.
On highways you can install huge 350kw chargers that can add hundreds of miles in the time it takes you to go to the loo and again chargers are incredibly cheap to install and require so little infrastructure compared to a gas pump.
The cost of a 4 pump gas station is about $500k[0], the cost of a 4 “pump” supercharger station is around $100k[1]. That’s 5x cheaper, and far easier to expand because you’re not dealing with flammable liquids.

> 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.
I've done 350~ mile trips pretty often (about 5 1/2-6 hours) and I usually only stop for 10-15 min to go to the bathroom and fuel up. Driving for a few more hours isn't really that bad, and very common in countries with 10x the square mileage of yours.
