By giving companies money.
Reminds me of a back and forth I had with an NYT staff writer who claimed it was "inhumane" to expect people to totally relearn a set of skills every ten years.
People seem to forget that how they "feeeeeeeel" doesn't matter. The job market dictates what you do and don't have to do, and we live in a time when you must consistently learn new skills to be competitive.
It is inhumane to expect people to relearn their skillset every decade on their own dime and time.
It's rare enough that companies pay for small-scale training - a full retraining is pretty much unheard of.
The board & management may have that plan but until they can sell electric cars that a) exist and b) dont spontaneously combust they wont get significant subsidies.
IMO what will really light a fire under their ass at this point, even if you forget about saving the planet, is that an EV is a lot more fun to drive than an equivalently price ICE (post rebates). Whenever I go back to an ICE vehicle for a rental situation, I tend to curse often at how sluggish it feels. Feels like an iPhone/Android vs Nokia situation, manufacturers will get with the program or they will get pounced out of the game by competitors.
