I think it is both a joke and not a joke. Literally, at the same time.
It is a joke as the $/kWh cost curve demonstrates (BEVs are simply taking over way faster than 2035) and it is NOT a joke as taxpayers are going to have to bail out legacy ICE if they fail. So putting out this deadline, IMHO, is a way of saying "look, we told you many years ago about this deadline, there is no bailout money waiting for you, you are on your own." There isn't much in this world that will piss me off more than to have to bail out legacy auto who have done everything they could to stop this transition.
So I honestly don't mind if GM and Ford are able to hold on for X or so more years, as by then Tesla (and actual competition) will have enough market share to keep the government from feeling that must bailout legacy ICE.
This exact scenario may play out in Japan much sooner (
Nissan is most likely
first and then
Honda) as automotive manufacturing is a large part of their
GDP.
And realize if a major OEM goes bankrupt, their major suppliers will be put into great distress, who are also supplying other major OEMs, thus starting a chain reaction of OEM to supplier to OEM to supplier
bankruptcies. Imagine Toyota, Nissan, Honda, Suzuki and Mitsubishi all going bankrupt within a few quarters and its effect on Japan's economy and then the rest of the automotive market?
