Don't they eat? Get tired? Need to relieve themselves?
The Ioniq 5 can charge itself from 10% to 80% (400km+ range) in 18 minutes. That's about the time it takes to stuff a gas station sandwich in your face and do a quick toilet run. Is that really a dealbreaker? Even when it's 80% cheaper to drive that way?
My new electric car takes like 30 mins for a "refuel" on decent charging infrastructure. And you know what? That's like 100% completely fine. I do like one of those massive road trips a year. Who cares if it adds like an hour or two to my total travel time. The electric is better in so, so many ways that it's the easiest tradeoff in the world to take a slight inconvenience once or twice a year.
My wife, kid, and dog and I drove from Sacramento area to Denver area to move. No big deal, it often offers a few choices for charging. Arrive at X with 30% battery, Y with 20% battery, or Z with 10% battery. Sure sometimes it would pop a notification and say "Keep it under 75 mph to get to charge with 15% left".
Cross country trips are easy, sure the stops are 10-15 minutes longer than I'd do personally. But often with 3 people + dog in the car that we wouldn't all be settled until after the car had plenty of range for a few options. Part of the dynamic is that low batteries recharge more quickly so we'd often go only 180 miles, but a stop ever 3 ish hours wasn't bad. Car often say charging at 550 miles/hour, so it's not particularly long to get most of a 300 mile range quickly.
I also assume that you don't have kids or other family when you drive - or you have trained your family extremely well :)
Oh wait, that happens every day at Costco.
I do think that it would be worth providing an incentive for businesses with big parking lots to cover at least some of the area with solar. The ground temperatures decrease (less heat island effect), less AC for nearby buildings, less AC in cars (which won't be as hot to begin with), and of course more solar power for the grid.
Tesla already does this: their systems automatically know where you need to charge and will reroute if all stalls are taken. The car will even heat the battery to optimal charging temperature to save charging time at the cost of range. But they have better vertical integration than other manufacturers.
Other manufacturers are slowly following. The tech is there, it's just an API call. But for now it's all in the hands of lawyers and MBAs.
