specialist insurance against the cost of replacement

Can't see it - it's not like a bet... the odds are very calculable and will hit everyone. Insurance works for rare, large, hard to calculate eventualities which benefit from shared risk amongst many punters.
What you want is for it to be a legal requirement for manufactures to recycle/repurpose after some level of degradation or being out of date; with trade-in or buyback.
That should be true for all electronics, electric motors and batteries... And we're slowly getting there.

Top end Tesla batteries are about £15k, less high performance ones about £10k. They have an expected life of 10-20 years, so that doesn't mean that the cars will be scrap at 10 years, but that from 10 years old they will have a declining battery performance and therefore value. End of life vehicle batteries are not without use, so will have some value to partly mitigate the high cost of replacement.

What about the labour cost? BMW man told me the i3 has 96 battery cells, each one has to be individually installed during the replacement process. That's why the lowly i3 battery is £20,000 to replace.

That's why they would assume known knowns such as degradation. The warranty on a car battery would be based on faults.

He's having you on. This is a picture of an i3 battery. A day's labour to swap over at most, say £1,000.

The 5 minute battery swap may be the future. Or rather the present because it is already here with the NIO, just needs standardising.

This has to be the future for EV's providing that there is enough infrastructure and they can keep the price down.

Each of the eight modules has twelve cells inside - 96 individual batteries:

Yes, absolutely, but then how many new "service stations" would we need?

Biofuel, using existing infrastructure must be the way to go once costs come down.

Your right it is all about the infrastructure and this would take time to build and then the government would want their cut in the way of tax, so it might work but were years away from this at the moment.

battery swap may be the future

Or just a stepping stone.
The boffins are chasing fast charging and high energy density (and not exploding) like crazy - the market is huge and the end point will be 100s of miles on a minute or two charging... Easily within 10 years

Indeed, but they come as one pack which gets bolted in as one. You replace the pack, not the individual cells one at a time. In the same way, the Tesla big battery has over 8000 cells, but they're not individually replaced. I think in the Tesla battery they come in banks of 512, so in the biggest battery version there are 16 banks.
