Like most people, my car is used for not just my regular trips around town, which I can certainly charge overnight no problem and be fine. My car is also used for the longer road trips.

It is 300 miles to my mom's house. Some electric cars could just make that in perfect conditions but give me a headwind or a cold day both of which happen once in a while and I can't make 300 miles on a charge and I will have to stop in the middle. At that point a fast charge is required. It is not acceptable to say I have to stop somewhere that I don't want to be for many hours to charge my car to get it the rest of the way. That is a trip where, if you have to make it, there isn't a better option. Flying would be even longer than driving by the time I get to the airport and rent a car on the far end, not to mention a lot more expensive.

At least in the U.S. it is very common for people to make a one or two thousand mile trip once a year for vacation. Particularly if you have a family, flying is not a reasonable cost and so you'll take those several days of driving to save money. Those road trips also let you stop someplace and see some weird small-town exhibit which is fun in its own way

I think the issue you're stuck on is driving an EV like an ICEV. When you're low on gas you stop, fill up, and continue. It's slightly different with an EV because you shouldn't fill up all the way on a stop. That takes so much more time because the batteries charge slower as they fill up. So if you want to get somewhere quicker you should actually be charging less at stops and stopping more often. I don't know about other cars but Tesla has a good route planner built in that does this for you and preconditions the battery while you travel to a fast charger, which is also important to reduce charge times.

My ancient 2015 Model S 70D would do that 300 mile journey with less than an hour of charging in the middle. A new car with much less time for charging.

I've just done a thousand mile journey from UK to Norway in that car. It was not a big deal to charge on the way and would be less so in a newer car.
