Electric cars can do 800+ miles a day easily with sold charging infrastructure. Sure, if you want to do a cannon ball run rent a car, but 4 hours of driving, get lunch, another 4 hours of driving, take a 30 minute break, 2 hours of driving, dinner anther 4 hours of driving get some sleep. That's an extra 30 minute break for 14 hour road trip.
That's a lot of downtime. Most people I know, including myself, when doing a 14 hour roadtrip would stop as infrequently as possible, for a total of 30-60min over the course of the trip. And that figure is including pee break stops, which your calculation presumably didn't.
It's actually really dangerous to do that kind of driving without taking significant breaks on a regular basis. But, sure if you do this regularly enough you can't either rent a gas car or spend an extra hour or 2 then fine. However, nobody I knew has done a trip like that in the last decade.
I think "really dangerous" is overstating it a bit. Driving while fatigued is dangerous, yes, but 14 hours with a 30-60 minute break is hardly that extreme, especially since we could be talking about road trips with multiple drivers.
It's a question of repetition not fatigue. People are just really bad at paying attention to limited stimulus. Swapping drivers every 4 hours or so is a good counter to https://en.m.wikipedia.org/wiki/Highway_hypnosis. But again if you have multiple drivers you only need one car that takes gas.
There's only one car that can go 4 hours on a charge, and that's the Tesla S. If you charge it for 30 minutes, it can go about another 2.5 hours.
My VW Golf TDI goes more than 750 miles on a tank at 65MPH. That's an entire days' driving for 5 minutes of fueling. Yes, the filthy Volkswageneers have to buy my car back, but it was certainly nice on the range.
While true, that range is from a 12,000$ battery pack which could be put in a 35,000$ car. So, really these cars don't have great range because they don't need to have great range.
