Fun fact: Planes are efficient for long trips. According to “sustainable energy without the hot air”, you need three people in a gas car to beat the efficiency of flying on a long trip. It seems like driving to LA with one or two people in the car is less carbon efficient than flying. With an EV you’re probably good though.
