Nevertheless, when they would do this, it's a serious effort/investment to introduce this on a soon to be outdated technology.
This exactly is the strongest argument for the winding down of ICE investment: the R&D effort is immense, the resulting product is a complex device impossible to keep in good working state without a network of advanced repair facilities, and it's still nowhere close to the efficiency of the most basic electric motor.
