The major automakers are half assing their EV strategy to prove a point that their legacy business model is better. The EV execs in the companies are being raked over the coals right now with the ICE execs crowing their career doom. Prices are too high, the charging infrastructure only exists for Tesla, etc etc. These were intentional outcomes orchestrated by the ICE executives to ensure they keep rising for the remaining years of their career. Some probably really believe fire and dinosaur juice Rube Goldberg machines are the future rather than fundamental forces like the electroweak force.

Their time is limited, and they will bring down the house with them. As you say, BYD, GW, and MG will eat them for lunch. I’ve been in their cars and they are pretty good, and have a lot of transferred tech from Tesla embedded at near zero R&D costs. With Tesla open sourcing their adapter design and getting federal subsidies to expand charger networks the Chinese makers just need to use the Tesla adapter and their infrastructure challenges are done.
