news In the future I expect technology to have improved to make them at least
as good as petrol cars.

While battery swapping might conceivably get close
time wise, there is no way to stop someone swapping
a good battery for a ****ed one and no way to test
how ****ed a battery is quickly and charge those who
show up with a ****ed battery for the cost of a new one
or just tell them to **** off with their ****ed battery.

Battery swapping is not feasible - the amount of space required to store them

would be ridiculous and constant swapping wouldn't do the connectors on the
battery or the car any good over time.

What about electrolyte swapping?

Lithium batteries don't use fluids.

Who said they had to be Lithium? There are many battery chemistries.

Anyway, I think you'll find there is gel inside Lithium batteries.

30 minutes is not feasible at all. Nevermind the inconvenience, think how big
refuelling stations would have to be!

There won't be refueling stations , there'd simply be charging points
scattered around the place - in car parks, supermarkets, streets etc etc.

Wherever they are, countless cars would be parked where they wouldn't normally be, taking up space.

The only sensible answer if they can't be charged instantly, is to have a range enough so that 99% of people can just charge them overnight at home. Mind you, that ****s up all those weird folk who have a car but no driveway.
