I think they will struggle, Tesla and the chinese companies have a lead on technology, better integration with battery technology and start from a clean sheet. Companies like Toyota have to play catch-up and build their EV business, while sustaining the ICE business where they make some profits, but which is in terminal decline, and service a pile of debt. I don't think anyone will want an ICE by 2030. I wouldn't buy one new now. If I buy another ICE, it will be a cheap 2nd hand stop-gap until I can get a cheap BYD, model 2 etc.
I think there be enough interest, might pick up a nice bargain . Second hand market might actually go nuts!
