most of the limited charging speed issues are solved by having big batteries, like if you didn't go out in weekends you can plug it in for a very long time to replenish.

by the way adding 250km for 6-8 hours a day is not that bad. back when i drive alot also less than 200km a day daily

Your point about early adopters is valid. They flush out unexpected/underestimated issues as well as positive issues. For eg, my friend was one of the first fifty who got the BMW iX xDrive40 so he has used it for just over a year. The WLTP range as per specification is 425 km but he achieves on average 360 km. He is considering swapping for the iX xDrive50 with a WLTP of 630 km. He has lots of moolah so no issue for him as an early adopter.
