I have no idea what a 1000 mile radius is good for. I would rather have 400 miles and a lighter car. There are some commercial applications maybe but nothing else?
Max charge rate is frequently dependent on battery size. A larger battery can absorb more power per unit of time. If you get 50% range in an hour of fast charging, the 1000 mile range car is much better for long distance travel.
Having to only charge your car every 1k miles opens up a lot of use cases. People living in places where they have to street park, and can't charge at night, might feel a lot better about electric cars if they only have to charge once a month.
Towing range is a major issue with the current generation of electric vehicles.
Auxiliary power uses are also appealing to a lot of people. 1000 miles of range can also translate to 500 miles of range and 100kw of power. Think about ambulances, cop cars and other service vehicles that just run their engines for an entire shift to keep the electricity flowing. Plenty of people travel with generators for personal and professional reasons. No need if your car has power to spare.
It's still all about charging in general. If it takes a 8 hours to deliver 50 and you drive 80 miles a day, you'll want a buffer of miles to prevent, having an extra buffer might get you through to a period where you aren't driving as much. Or you can make longer trips without refill. Or you can worry less about inefficiencies at lower temps.
Lots of good examples in the replies, but also quoted range tends to be best-case scenarios. Ideal temperature, not running the cabin heat, etc. In the real world, I want to be comfortable that on a -5F winter morning that I can defrost the windows and heat up the cabin and with cold-soaked batteries still get through my day of driving.
It will be a luxury item. Unless batteries become incredibly cheap and lightweight, economics will strongly favor a car that has just the right amount of range and no more.
However, some people have extra money to spend, and range is a meaningful upgrade. With gas vehicles, there are already people who get a much bigger vehicle than they really need and are willing to pay way more for the vehicle and for fuel. I don't see any reason not to expect the same with electric cars.
About EV motor homes: battery capacity for domestic use is plenty in any EV. Powerwalls have much less capacity. So I'd buy a EV motor home with minimal range, like 100 miles. When stationary the capacity is only limited by the solar panels on top (~1.5kW peak). Then again, maybe my use isn't typical.
I'd wish for solar panels mounts as standard for EV vans, with potentially full roof coverage.
