> Once those IC cars are no longer manufactured, we can expect a very rapid ramp-down of extraction and distribution industries for petrol and diesel fuels, leading to a complete phase-out possibly as early as 2040. As about half of global shipping is engaged in the transport of petrochemicals or coal at this point, this is goin to have impacts far beyond the obvious.

I wouldn't be too sure about that. Most electricity is still generated by burning fossil fuels. Solar and wind have increased in recent years but still have a very long way to go. We may just be relocating the engines rather than decarbonizing.

(See also, New York City banning gas lines to new construction, requiring the use of electricity for heating and cooking, just after the metro area's sole nuclear plant was decommissioned and new gas plants were built to replace it... so the ban is not going to reduce the amount of gas burned at all, is it?)
