I watched a bit of a slide show on one trade stand that quoted some research that said the market will be 40/30/30% divided between full EV/hybrid of any kind/ICE. That suggests that there will still be quite a proportion of ICE in to the future.

What would worry me is that the investment in technology, battery, platform for ICE engined cars will diminish significantly. As the electric/hybrid tech develops and comes to market it probably means we are within 3-4 years of peak ICE technology development.

The cost of development of the electric platforms mean development sharing between manufacturers which probably means less diversity and probably a further round of consolidation in vendors, if not brands.
