I mean, Tesla is already 100% electric so the emphasis is on incentivizing / forcing the other automakers to accelerate electrification. When we think about it, they sell way more cars than Tesla, so from a practical point of view you want to move them. Besides forcing (laws, emmissions standards) you can also praise them foe their work in order to get them more on the electrification agenda.

Praising Tesla wouldn’t increase electrification, so doesn’t seem worth doing unless it would stoke sufficient envy to encourage other automakers.

Sour grapes about not being praised seems more an ego thing.
