Elon uses four personal jets guzzling who knows now much gas. He practically flies 24x7. When it comes to climate, he is a hypocrite.
His "guzzling" jets as you call them are a minor convenience in order to facilitate quicker, more efficient transport to enable the evolution and development of Tesla and SpaceX.
Do you expect him to drive everywhere? Not only would that be worse for the environment, but it would mean more of Elon's precious time wasted and thus also our time wasted because a brilliant man is stuck in traffic.
