You need to factor in that China is pushing heavily for EV and Chinese car manufacturers will handle part of the demand for cheaper EV in China and other countries.
Same for India, Tata will probably not stop making combustion engines for a while but they will have to produce cheap EV for their market and abroad.
Toyota may resist for a while but they will lose market share in luxury and middle-range cars as combustion engines get banned or at least restricted in wealthy countries and will remain too expensive for emerging markets.
So Toyota may end up producing the cheaper models of ICE cars only.
