The basic breakdown of usable mileage for an EV looks like this:
1) 10% of range is lost in the first 30K miles
2) 10% of range is not used for fear of running out of charge (bottom 10%)
3) 10% of range is not used to keep battery from degrading prematurely (top 10% AKA only charge to 90%)

The next point is that charging a battery in an EV is like filling a glass up with water and not spilling any.  The battery charges at full speed for the first 50% then starts slowing down.  the time taken to fast charge from 80-100% is about the same time as from 10-80%.  Having a bigger battery makes charging go faster since you don't have to go up to 80% or higher to get decent usable range.

With these basics in mind, you already lose 1/3 of the rated mileage without doing anything.  So a vehicle with 450+ miles will give you 300 miles usable if you don't go faster than 65 mph or live in a very cold climate.  Until cars have stated ranges in excess of 450 miles, they won't be effective for taking long trips compared to ICE cars.  Once EVs have 500+ miles of stated range, then they are direct replacements for ICE vehicles.

400 EPA miles are not actual miles outside the 30 mph zone. If doing 80 mph on a highway, you'll be closer to half of stated EPA range. Especially if you need AC or heating.

That's why 600 miles is interesting, as you get 300 miles real range. For inner city driving, of course 200 miles real range is OK.

Thanks, will keep that in mind. Goes to say how bad the actual mileage of the competition who don't even meet EPA 400 is though...

High Ni batteries will be too expensive to see widespread use. 

Yeah, yeah, yeah - 'will', 'can', 'planned', 'scheduled' - come back in 2023 with a real product and we'll talk 🤣

Besides, these 400 mile cars are not able to cover 400 miles doing motorway speeds. At 80-90mph range drops closer to 200 which would make you stop to charge after less then 3h which is poor.

after 400 miles a driver does need to stop for sleep or s***, but one might not have a charger at hand or not want to put the car to charge. so a 600 miles car does make sense.
