Legacy automakers EVs are just ICE cars with the engine swapped out. Whereas BYDs, teslas etc are a ground up rethink, vertically integrated with battery manufacturing and software.

Classic innovators dilemma - it seems to be almost impossible to align incentives inside legacy auto to do the necessary revolutionary change. Every individual and sub group are internally invested and short term focused on their legacy frames, drivetrains, layouts, electronics, software and supply chains. That’s why you keep getting offered the same car, but now as a sub par EV. So they will lose, because they can’t adapt.

They are getting a lot better in the drivetrain at least, watching videos of teardowns (like Munroe Live) - a couple of years ago a lot of the legacy car brands were using OEM motors and inverters etc. from companies like Bosch, but the newer models are getting a lot more advanced. Probably Lucid had the nicest motor and electronics package and everyone seems to have converged on motor windings a lot like theirs (including Tesla and the legacy brands).

But there is still a lot to be desired in legacy EVs, but generally at least some of the brands are slowly moving in the right direction.
