In 2024 it's borderline OK not to have an EV business. EV's are 10% of the American market, 25% of the European market and >50% of the Chinese market. The Chinese market is probably lost anyway due to the insane local competition, so concentrating in 2024 on the larger share of the market outside of China is reasonable.
Let's say that the flipover point is 2027.
And let's say it's 2027 and you're looking to buy an EV. You narrow down your choice to a 3rd generation Tesla, a second generation Ford or VW and a first generation Toyota or Honda. Reliability is the deciding factor. What do you choose? Lots of people are going to choose a Japanese brand despite any drawbacks getting a "bleeding edge" model entail.
By not ramping up EV production gradually they're setting themselves hard production and logistics problems. All new production processes have teething problems, and they're a lot easier to solve when production is in the 5 figures rather than when it is in the 7 figures, but if anybody can solve hard production and logistics problems it's probably Toyota.
