My company pays for taxi from my door to the airport and I still take the train, unless I am leaving before dawn.

There is both a rational environment choice in that, and a nice feeling of being part of a humming crowd

I drive an EV powered by my own solar panels. I’ve done my part and frankly don’t much like public transport unless I’m specifically looking to be in the hubbub which is mostly on the weekends when I’m socializing.
