Car for a lot of reasons;
-freedom to go wherever you want whenever you want
-privacy - no irritating drunks telling some stupid stories (like in a bus or subway)
-freedom to choose your own music
-no schedules to catch, no worries
-no hassle with the luggage, take what you want and feel safe that it`ll get to that same destination as you
-in a car my destiny is in my own hands. I always feel more comfortable when I don`t have to trust my ass on the mercies of someone else - especially if I don`t even know that person - or even see him, like the pilot in a plain, ship or train.
-...and then there`s those airports of today with the safety hassle, plains missing their schedules, airplane food etc...yeah, flying is a real joy these days....
And the most important thing; I love driving, it`s pure relaxation for me, no matter what the traffic or road conditions are like. Except congestion if I`m in a hurry.
