Since when was life that predictable?
Compare and contrast:
You go to work for the day, come home and at some point in the evening a family member is taken ill and needs to go to hospital. This may not be life threatening, in which case the Ambulance service wont respond, they will expect you to do it yourself (not unreasonably, in the case of non-emergency admissions)
You: "Right, lets go, I'll make a quick stop at the petrol station on the way because I was going to go there in the morning before work"
After a short delay, you arrive at the hospital
Electric car charged to the minimum requirements for expected use
You: "Dammit, the battery is flat and there won't be enough charge in the car for several hours"
Result: Unnecessarily long delay in arriving at hospital and your loved one being treated.
Now, I realise this is a very specific circumstance, but it usefully illustrates the wider point that life simply is not that predictable. In the case where cars can charge to at least 80% of their total capacity in 10 minutes, this would be useful. As it is currently more like 10 hours, sorry, I don't see it.
I know there is an overhead (possibly quite a big one) in using hydrogen to power a fuel cell, and for this reason many see it as unsuitable, but as technology improves, that overhead will drop and you can still fuel your car in a matter of minutes, plus we handily avoid many problems of overloading the national grid at peak times, running cables across the pavement for those without driveways and so on.
