What they say they will do, and what the customers will really buy in a couple of years may very well differ a lot. You will get the market very quickly to 60% or maybe even 70% EVs. But not all people will buy an EV.
Some people still use landline phones and internet connections.
Some people still go to a shop to buy stuff instead of Amazon.
Not all people fly with low fare airlines.
Not all people get vaccinated.
Some people only eat meat once a week...
So some people will still want a gas powered car. For whatever reason (valid or even "just cause").
So even Lexus will still sell a couple of gas powered cars. Or just miss out on a not insignificant portion of the market. Mark my words
