Sure, you can optimize for different things. You could argue that the best way to travel alone is by private jet. You get there quickly and in luxury, with a birds-eye view, and have food and drinks served the whole way by your chef. It's all subjective.

Private jets can only travel between airports. So they are useless for short range travel.

I guess if you can afford the jet, you can afford to have a helicopter waiting to pick you up?

I look at the elephant in the room : CO2. Measured, not subjective.
