This approach using repurposed Tesla batteries seems more of a proof-of-concept than anything (although that's entirely fair, given they currently produce [probably] the best examples).

However, this is probably the tip of an iceberg to come. There is a huge amount of value worldwide in collectible/exotic/classic cars - values have soared since the '08 financial troubles, to the point of some cars becoming pure investments, rather than something to drive.

As we move towards a world where the ICE will become extinct, what will happen to all of this automotive history? A few options:

* huge devaluation

* exemptions (to the ICE ban) for such cars... but at an increasing cost, as presumably petrol would become increasingly expensive and difficult to source

* widespread drive-train conversions, allowing such cars to be enjoyed in perpetuity
