An EV doesn't need to have 480 miles of range. Nobody is driving that distance daily. 98% of trips are under 50 miles. Only 0.8% of the trips are over 100 miles!

Also, EVs use regenerative braking. That should help a little bit.

EVs should be built with 100 - 150 mile range. All families with 2 cars can immediately switch one of their cars to a daily driver EV and the other vehicle is a minivan. There are lots and lots of people for whom an EV works perfectly well and if they need to go longer, US has a robust rental car industry. What would help is to let people charge anywhere they park. All workplaces should offer free charging, and companies can negotiate to get paid for charging their employees cars. The price of electricity goes negative because of lack of demand, and this is something that they can offer to the grid, demand as a service.

As an EV owner myself, no. Absolutely not.

The reason is simple: The mere existence of low-range EVs hurts overall EV adoption, because people aren't going to rent a car just for a road trip. You're talking about adding $100+ per day on what's supposed to be a cheaper method of travel compared to flying.

ICE-holes don't think critically. They don't care that long range EVs exist. They'll just see one that only gets 100-150 miles of range and go "See? EVs have short range. They're not appropriate for road trips. That's why I'll never get one.", despite plenty of 250+ mile options.

Now, I suppose you could argue that this type of person would simply never get an EV and would just come up with a different reason, and you'd probably be right. But the general point still remains: People want a car that satisfies ALL their needs and won't settle for something that works "only" 98% of the time.

Not only that, but with a longer range, you have more flexibility in planning recharging. It may take more time to top up from 50 km left to 500 km, but you have more flexibility about when to do it. Something that needs a daily charge is going to be interfering with your schedule.
Exactly.

Having only a 100 mile range is plenty for your daily driving, but if you can't charge at home, it becomes very disruptive.

Short range EVs typically only support J-1772 which only charges at up to 19.2 kW, and many cars only even support 11.5 kW. You'll be charging for at least an hour.

At least with a 300 mile range, most people could get away with charging for just 20 minutes/week.

Just wait for people to be priced out of ICE cars. EV's should be and will be significantly cheaper to buy and manufacture.

Sure, ubiquitous charging will be enormously helpful to adoption, and universal rapid charging also. But the reality is it doesn't yet exist.

Until then, just because long trips are lower frequency does not mean they are less important or can be ignored as a requirement, particularly if a person/family has only one vehicle.

The long trips may be the most important trips, maybe to see family only a few times a year...

Plus, even though you might be able to rationalized away the long range requirement, generations of people are accustomed to cars yielding 4-600 miles between fill-ups. It is not only the ability to drive on a long trip, but also the need to only fill up your car every 1-3 weeks instead of every day or two.

Desirable Range between fill-ups is also a human-factors issue. You want the range of the car to be at least, indeed around, the distance people can drive in a single stint. If you can drive 350 miles in 4.5 hours, and your car gets that distance, you're probably OK resting and filling up. If it goes 1000 miles between fill-ups, that isn't a big advantage. But if the car makes you stop before you feel you need to stop, that will feel like the car is not good enough for your needs.

So, sure, if we suddenly got 2500 Wh/kg batteries and could easily make cars with a 1000-mile range, and manufacturers offered 1000, 500, and 100-mile ranges, I'd expect the most sales to be in the 500-mile units.
